When it comes to laser hair removal, there is a few things to keep in mind, namely, to stay away from the following:
- wax or pluck your hair out 4 weeks before and 4 weeks after the laser hair removal treatment. The laser needs to “see” the dark pigment in the root of your hair in order to destroy the blood supply to it and, therefore, stop the follicle producing hair. If you take out the hair root, there will be no pigment for the laser to “see” and the treatment will not work;
- sunbathe or be in the direct sun exposure 4 weeks before and after the laser treatment. During a laser hair removal treatment, melanocytes get activated. By exposing the treated area (and the area to be treated) by laser to the sun, melanocytes get activated even more that increases the risk of hyperpigmentation and even burns ;
- take supplements containing vitamin D two weeks before and after a laser treatment as it activates melanocytes that can increase a risk of skin damage during a laser treatment;
- pick on shedding hair after a laser hair removal treatment. It may increase the risk of infection;
- go to steam room or sauna or a swimming pool or take a hot shower a few days after a laser treatment as it may lead to skin burns due to increase skin sensitivity after the laser treatment;
- wear tight or rubbing clothes right after the treatment to avoid friction that may lead to skin irritation and and may cause substantial burns to the epidermis;
- apply deodorants or other perfumed substances on the lasered areas. It will irritate the skin that is sensitive after a laser treatment.
The effect of vitamin D on hair growth and pigmentation
Vitamin D and Unwanted Hair Growth
Excessive growth of unwanted hair (also known as hirsutism), often associated with conditions, such as polycystic ovary syndrome (PCOS), is primarily driven by elevated androgen levels in women. Androgens, such as testosterone, can stimulate excessive growth of coarse, dark hair in the areas where women typically have minimal hair. PCOS is a common endocrine disorder that affects reproductive-aged women, and one of its hallmark features is hyperandrogenism. Vitamin D, a hormone-like nutrient, has been shown to influence the endocrine system and regulate hormone levels, which may have implications for hirsutism.
Studies have highlighted a significant prevalence of vitamin D deficiency in women with PCOS. This deficiency is often correlated with more severe symptoms, including insulin resistance, which is a major driver of PCOS-related hyperandrogenism. Insulin resistance contributes to increased androgen production in the ovaries, exacerbating hirsutism. Interestingly, a study published in Clinical Nutrition examined the effects of vitamin D supplementation in overweight women with PCOS. The results showed that weekly doses of 50,000 IU of vitamin D₃ not only improved serum vitamin D levels but also reduced androgen concentrations and hirsutism scores. These findings suggest that vitamin D may indirectly influence hirsutism by improving metabolic and hormonal parameters in women with PCOS. However, while vitamin D supplementation appears promising, it is not a standalone treatment for hirsutism and is most effective when combined with other therapeutic approaches.
Vitamin D’s impact on hormonal balance extends beyond PCOS. The vitamin interacts with the hypothalamic-pituitary-gonadal axis, which regulates reproductive hormones. Adequate vitamin D levels may support the normalisation of this axis, potentially reducing the severity of hyperandrogenic conditions. While more research is needed to establish a direct causal relationship, these findings underscore the importance of maintaining optimal vitamin D levels for hormonal health.
Vitamin D and Phases of Hair Growth Cycle
Hair follicles are highly dynamic structures that undergo cyclical phases of growth (anagen), regression (catagen), and rest (telogen). These phases are regulated by a complex interplay of hormonal, genetic, and environmental factors. Vitamin D receptors are expressed in the epithelial cells of hair follicles, suggesting that vitamin D plays an essential role in the regulation of hair growth. The presence of these receptors indicates that vitamin D may influence the initiation and maintenance of the anagen phase, where active hair growth occurs.
A deficiency in vitamin D has been associated with various hair disorders, including alopecia areata (hair loss), telogen effluvium, and androgenetic alopecia. However, its role in hirsutism (unwanted hair growth), characterised by excessive rather than reduced hair growth, remains less clear. Research has proposed that optimal vitamin D levels could support healthy hair follicle function by modulating cell proliferation and differentiation within the follicle. By promoting a balanced hair growth cycle, vitamin D may help reduce abnormal growth patterns, although more studies are needed to confirm this effect in cases of hirsutism.
An interesting development in vitamin D research involves the measurement of vitamin D levels in hair itself. A study published in Nutrients introduced a method to assess 25-hydroxyvitamin D concentrations in human hair, providing a non-invasive approach to determine vitamin D status. This breakthrough underscores the close relationship between vitamin D and hair biology, offering new opportunities to study its impact on hair disorders. While this research primarily focuses on hair loss conditions, it opens the door for future investigations into how vitamin D might influence excessive hair growth as seen in hirsutism.

Vitamin D and Hair Pigmentation
Hair pigmentation is determined by the amount and type of melanin produced by melanocytes, specialised cells located within hair follicles. Melanin production is influenced by several factors, including genetics, hormones, and nutritional status. Vitamin D may play an indirect role in hair pigmentation through its regulatory effects on melanocytes and melanin synthesis. The interaction between vitamin D and melanocytes occurs via specific receptors, which are also involved in the broader regulation of skin and hair pigmentation.
The “vitamin D–folate hypothesis” provides an evolutionary framework for understanding the relationship between vitamin D and pigmentation. According to this hypothesis, skin pigmentation evolved to balance the synthesis of vitamin D and the protection of folate under varying levels of ultraviolet (UV) radiation. While this hypothesis primarily addresses skin colour, it suggests that vitamin D levels could influence melanin production in hair as well. For example, low vitamin D levels might affect melanocyte activity, potentially altering hair pigmentation.
In the context of hirsutism (unwanted hair growth), hair often appears darker and coarser due to androgen stimulation. Although the role of vitamin D in this process has not been fully explored, it may be conceivable that vitamin D influences the pigmentation of excessive hair growth. By modulating melanocyte function, vitamin D may indirectly affect the colour and texture of hair in individuals with hirsutism. Further research is needed to clarify this relationship and determine whether optimising vitamin D levels could impact hair pigmentation in such cases.
Supplements Contraindicated to Laser Hair Removal
Certain supplements and medications can interfere with laser hair removal treatments, either by increasing the skin’s sensitivity to light or affecting the skin’s ability to heal after the procedure.
- Some supplements are known to cause photosensitivity, meaning they make your skin more reactive to light. One of the most well-known culprits is St. John’s Wort, a popular herbal remedy often used for mood enhancement and mild depression. St. John’s Wort may cause photosensitivity, which may increase the risk of burns or hyperpigmentation when exposed to light-based therapies such as laser hair removal. Similarly, vitamin A derivatives, including retinoids and retinol, are powerful compounds often used to improve skin health or treat acne. Retinoids have been shown to thin the epidermis and increase skin fragility, making the skin more prone to damage during procedures, such as laser treatments. Even oral forms, such as isotretinoin, are reported to delay wound healing, which is why our laser hair removal practitioners recommend avoiding these products 4-6 months before laser hair removal.
- Another category to consider is supplements that affect blood clotting or blood circulation. For example, vitamin E, which is widely regarded for its antioxidant and anti-inflammatory benefits, may act as a mild blood thinner when taken in high doses. This can lead to increased bruising, redness, or sensitivity after laser hair removal. Similarly, natural supplements, such as garlic, ginger, and ginkgo biloba can also thin the blood, which might result in heightened post-treatment side effects. While these supplements are beneficial for general health, their impact on blood circulation can make the skin more vulnerable to bruising or prolonged healing following laser exposure.
- Hormonal supplements can also influence the outcomes of laser hair removal. DHEA (dehydroepiandrosterone), a hormone precursor often marketed for boosting energy, mood, or libido, may impact the efficacy of laser hair removal. DHEA influences androgen levels, which could stimulate hair growth and may counteract the effects of the treatment. Similarly, herbs, such as licorice root, which contain phytoestrogens, have hormonal activity that may alter the growth cycle of hair and potentially interfere with long-term laser hair removal results.
- Interestingly, some antioxidants, while generally good for skin health, may also interfere with laser hair removal. Vitamin C and Vitamin E, for instance, are powerful antioxidants that reduce oxidative stress and inflammation. While this is excellent for general skin health, in the context of laser hair removal, these properties may dampen the controlled inflammatory response that the laser creates to destroy hair follicles. This might reduce the efficacy of the treatment, particularly if taken in high doses around the time of the procedure.
If you are planning laser hair removal treatments, there are several steps you can take to minimise the risks and maximise the results.
- First, always inform your laser therapist about any supplements, medications, or skincare products you are using. This information will help our practitioners tailor the treatment to your needs or advise you to temporarily pause certain products.
- It is also crucial to follow the pre-treatment instructions provided by our laser practitioners. This often includes avoiding direct sun exposure, tanning beds, or self-tanning products, as these can increase the skin’s sensitivity to the laser and increase the risk of burns or hyperpigmentation.
To address any concerns about how your supplements or medications might interact with the laser procedure, we always invite our clients to come for a laser at least 72 hours before the actual treatment.
Supplements Recommended to Laser Hair Removal
Supplements recommended for laser hair removal are primarily aimed at supporting skin healing, reducing inflammation, and promoting optimal skin health. These supplements can be beneficial before or after treatment to minimising side effects, aid recovery, and ensure the best possible outcomes. Laser hair removal creates controlled damage to hair follicles and the surrounding skin. Taking supplements that may enhance skin repair and resilience may play a beneficial role in recovery and results. Below is an in-depth exploration of some supplements that may be helpful, followed by a useful table of the supplements that may be considered if you planning or going through your laser hair removal course of treatments.
- Zinc is one of the most important minerals for skin repair and wound healing. It is essential for cell regeneration, maintaining the integrity of the skin barrier, and controlling inflammation. After laser hair removal, the skin undergoes minor trauma, and zinc may support the healing process by facilitating tissue repair and reducing redness or irritation. Zinc has been extensively studied for its role in promoting skin health and wound recovery, making it a beneficial addition to post-treatment care. The role of zinc is recognised in maintaining skin integrity and promoting faster recovery from minor injuries, which may be particularly relevant for laser-treated skin.
- Vitamin C is another key nutrient that offers a wide range of benefits for skin undergoing laser treatment. Known for its powerful antioxidant properties, vitamin C may help protect the skin from oxidative stress caused by laser. Additionally, it is critical for collagen synthesis, which may aid in repairing the dermal layer of the skin. By reducing inflammation and promoting cellular turnover, vitamin C may accelerate the healing process and minimises the risk of hyperpigmentation or prolonged redness. Consult our nutritional therapist to learn more about the effectiveness of vitamin C in supporting dermal healing and calming inflammation if you are undergoing laser hair removal.
- Vitamin E is widely regarded for its ability to hydrate and protect the skin. While high doses of vitamin E may thin the blood and should be avoided immediately before laser treatment, moderate doses after the procedure may aid in recovery.Vitamin E may reduce inflammation, help maintain skin hydration, and protect the skin from free radical damage. These properties make vitamin E particularly useful for calming redness and irritation after the laser treatment. Contact our laser practitioners to find out how vitamin E may help you as a post-laser care supplement.
- Collagen peptides, derived from hydrolysed collagen, are supplements that support the skin’s elasticity and hydration. Collagen is a key protein that forms the structural framework of the skin. After laser treatments, collagen synthesis may be essential for tissue repair and resilience. Taking collagen supplements may improve the skin’s ability to recover by strengthening the dermal layer and minimising potential scarring or irritation. Clinical trials have shown that collagen peptides may improve overall skin health, hydration, and wound healing, making them a potentially beneficial supplement for laser hair removal recovery.
- Omega-3 fatty acids, commonly found in fish oil, linseed oil (also known as flaxseed oil) and avocado are known for their anti-inflammatory properties and ability to support skin repair. These fatty acids may help reduce systemic inflammation and enhance skin’s resilience, which may be helpful in mitigating post-laser redness or swelling. However, it is important to use omega-3 supplements with caution, as they may have mild blood-thinning effects. This means that they should not be taken immediately before your laser treatment but can be safely incorporated after the laser procedure to support healing. Scientific studies have confirmed omega-3s’ ability to improve inflammatory skin conditions and promote faster recovery, making them a valuable addition to your laser aftercare routine.
- Hyaluronic acid, often recognised for its topical benefits, may be also effective as an oral supplement. Known for its hydrating properties, hyaluronic acid may improve skin elasticity and moisture retention, both of which are crucial after laser hair removal treatments. Oral supplementation ensures that the skin remains well-hydrated, helping it recover more efficiently from laser-induced trauma.
- Probiotics are another promising supplement for skin health, particularly through their effects on the gut-skin connection. By balancing gut microbiota, probiotics may help regulate inflammation and enhance the skin’s natural barrier function, which may be temporarily compromised after laser hair removal. They also play a role in reducing redness and promoting faster healing. To learn which probiotics may be good for you as a post-laser care, please contact our nutritional therapist.
As with any supplement, it is essential to consult with a qualified practitioner before starting a new regimen, especially if you are undergoing laser hair removal. They may help determine the right supplements for your individual needs and medical history, ensuring that you achieve the best results while minimising potential risks. By combining professional guidance with a thoughtful supplementation plan, you can support your skin through every stage of the laser hair removal process.
