Collagen is often associated with elective cosmetic procedures to help reduce the appearance of lines and wrinkles. However, collagen, which is essential for healthy skin, hair and nails, is also a naturally-occurring protein found in the human body. A collagen supplement can be especially effective for the growth and maintenance of healthy hair.

Collagen can help build hair's protein and prevent split ends.

Benefits

Collagen makes up nearly 25 percent of the body's protein and is essential to the function of connective tissues. Collagen, in cooperation with elastin, allows the skin to stay firm and the joints to stay limber. It also has many anti-aging properties.

Hair Loss

As you age, the natural levels of collagen present in your body decrease. Collagen, when taken as a supplement, has been shown to support and increase the body's hair-building proteins. This can lead to longer and thicker hair. The recommended dosage for hair regrowth and bulking for aesthetic purposes is 5 to 6 grams.

Grey Hair

Collagen may help reduce the appearance of grey hair by supporting the healthy structure of the hair follicle, which is where the pigment that gives hair its color is produced. When applied directly to the scalp, collagen creams and gels can make grey hair appear darker and less dry.

Split Ends and Breakage

Collagen can be very effective in treating dry, brittle hair. Collagen supplements and topical products are effective in repairing and reversing split ends as well as supporting healthy moisture levels within the hair.
