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

Collagen has many positive effects on hair.


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 g.

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 has been shown to be very effective in the treatment of dry brittle hair. Hair can become dry and course over time. Collagen supplements and topical products are effective in repairing and reversing split ends as well as supporting healthy moisture levels within the hair.
