hair growth is still ongoing , its high concentration of antioxidants , particularly vitamin E , is thought to protect hair follicles from oxidative stress . A study published in the International Journal of Cosmetic Science found that rice water improved hair elasticity and reduced surface friction , potentially leading to stronger and more resilient hair ( Inamasu , 2010 ). More clinical research is required to validate its effects on actual hair regrowth .
Grape Seed Extract : A Potent Antioxidant Grape seed extract is rich in proanthocyanidins , powerful antioxidants believed to promote hair follicle health . The extract may enhance blood circulation to the scalp , which could aid in nutrient delivery to hair follicles and stimulate hair growth .
A 2023 study showed that proanthocyanidins exhibited excellent antifungal activity and increased the proliferation of hair follicle cells , suggesting their potential in anti-fungal activity also supporting hair density and length ( Yarovaya , 2023 ).
Zinc : A Key Mineral for Hair Follicle Health Zinc is an essential mineral that plays a pivotal role in hair tissue repair and growth , as well as for the maintenance of the sebaceous glands surrounding hair follicles . Zinc deficiency has been linked to hair shedding and thinning , making supplementation potentially beneficial for those lacking adequate levels .
A study published in Annals of Dermatology highlighted those individuals with alopecia areata and telogen effluvium showed lower zinc levels compared to healthy controls ( Park , 2009 ). Supplementing with zinc in such cases may help restore hair growth . However , excessive zinc intake can lead to negative
side effects , so it ’ s important to maintain a balanced dosage .
Vitamin D : The Follicle Rejuvenator The role of Vitamin D in the formation of new hair follicles may stimulate dormant follicles , promoting new hair growth . Vitamin D receptors in hair follicles are essential for promoting the anagen phase of the hair growth cycle and regulating keratinocyte differentiation and proliferation .
Low levels of vitamin D have been linked to hair loss conditions such as alopecia areata , and supplementation has been shown to help prevent and even reverse this condition in some cases ( Saini , 2021 ). Studies found that patients with alopecia areata had significantly lower serum vitamin D levels compared to a control group .
In summary , the world of hair growth supplements is filled with promises , but not all are backed by strong scientific evidence . Proteoglycans and saw palmetto have shown promise , particularly for individuals with hormonal or stress-related hair loss , while zinc and vitamin D are essential for overall follicle health , especially in cases of deficiency . Meanwhile , the benefits of biotin , Oryza sativa extract , and grape seed extract are more mixed , with limited clinical data to support their effectiveness in promoting significant hair regrowth for those without specific deficiencies .
Consulting a healthcare expert is essential to ascertain the underlying reasons of hair loss and to establish the most effective treatment plan . In several instances , a balanced diet , effective stress management , and appropriate hair care can enhance or surpass the efficacy of supplements in promoting healthy hair . aesthetics . globalhealthasiapacific . com ISSUE 4 | 2024
