Rating (out of 5): 2

Algae, particularly varieties such as spirulina and chlorella, are increasingly incorporated into hair care formulations and supplements due to their rich nutritional profile. Scientific evidence suggests that algae are high in proteins, essential fatty acids (like omega-3), vitamins (such as B vitamins and vitamin E), minerals (including iron and zinc), and antioxidants, all of which are important for hair health. Small studies and in vitro data indicate that algae extracts can help protect hair follicles from oxidative stress and may support scalp health due to their anti-inflammatory properties. Additionally, anecdotal and preliminary clinical reports point to algae’s ability to improve hair strength and possibly reduce hair thinning by providing nutrients that support healthy hair growth cycles. However, high-quality, large-scale clinical trials directly linking algae supplementation or topical use to significant improvements in hair growth or quality are currently lacking. Most available evidence comes from biochemical analysis and limited human studies. Therefore, while the use of algae for hair health has some scientific basis, the direct impact remains moderately supported, and further research is warranted to confirm efficacy and optimal usage.
