Many people know collagen benefits skin and joints, but what does collagen do for hair?
Collagen is made of the amino acids proline, glycine and hydroxyproline, which comprise the proteins used as the building blocks for skin, muscles, bones, tendons and ligaments, and other connective tissues. As we age, the body produces less collagen.
To stimulate collagen production, proper nutrients are necessary. Collagen supplements, hyaluronic acid, vitamin C, aloe vera gel, ginseng, antioxidants, retinol and beta carotene (derivatives of vitamin A), light therapy, sunscreen, and limiting caffeine and tobacco exposure may help.
Collagen supplementation, specifically, can help skin maintain its elasticity and cushion weakened joints, but there is limited evidence regarding what it can do for hair.
What Does Collagen Do for Hair?
Several studies have been conducted regarding collagen’s effects on hair. One study looked at the hair growth-promoting effects of a fish collagen peptide. It found that collagen peptides could benefit hair loss and regrowth for people with alopecia.
In another study, participants showed a better response when taking a food supplement containing hydrolyzed fish collagen combined with other hair treatments as compared to participants who combined treatments with a placebo. However, the study had several limitations including a small and unbalanced sample size. It was also a short-term study lasting just 12 weeks.
Biotin vs. Collagen
Both collagen and biotin have been used for hair regrowth, but which is better?
A small 2021 study looked at hair loss in women who had weight loss surgery. Of the 156 people in the study, 22 had a biotin deficiency. Five of those people reported a reduction in hair loss with biotin supplementation.
Additional research shows that 11 out of 29 people with a biotin deficiency showed significant declines in hair loss with biotin supplementation.
There are limited results regarding biotin and collagen’s potential as hair regrowth remedies. However, biotin may be more effective for people with biotin deficiencies.
Are Collagen Supplements Bad for You?
Collagen supplements may or may not support hair regrowth, but they can improve skin elasticity and joint health. If you take them, hair regrowth may be an added benefit. However, there are some possible side effects to be aware of as follows:
- Supplements are not FDA-reviewed for safety and effectiveness. While most supplement companies conduct testing, you are always taking a risk when using a supplement. Source products from a reputable brand to ensure the best outcomes.
- Some research revealed that collagen supplements may contain trace amounts of heavy metals.
- Collagen supplements should not substitute for proper skincare. Refrain from smoking, eat a healthy diet, use sunblock, and get enough sleep to maintain skin health and recommended collagen levels.
