Can Nutrition Affect Hair Growth?
Tocotrienols--a natural compound related to vitamin E--may increase hair growth by as much as 34%
Hair loss can cause low self-esteem and a lack of confidence in both men and women. Now a study in Tropical Life Sciences Research holds promise for hair-loss sufferers and reports that tocotrienols--a natural compound related to vitamin E--may increase hair growth by as much as 34%.
Counting the hairs on your head
Vitamin E is made up of four tocotrienols and tocopherols, respectively called alpha, beta, gamma, and delta. In this study, 38 people (mostly men) with hair loss, were randomly assigned to receive 100 mg of mixed tocotrienols plus 46 IU of vitamin E (alpha-tocopherol) or placebo daily for eight months. The number of scalp hairs in a specific area of each participant's head was monitored at four and eight months.
The tocotrienol group experienced an average of 34% more scalp hairs compared with the placebo group who experienced a slight decrease. There was no significant increase in the weight of hair clippings in either group during or after the intervention.
The study authors comment, "A possible explanation for the effects could be due to the potent antioxidant activity of tocotrienols that help to reduce lipid peroxidation and oxidative stress in the scalp, which are known to be associated with alopecia (hair loss)." This is a small study, and further research is needed to investigate and confirm the role of tocotrienols in preventing hair loss.
