Some people say aloe vera helps with hair growth, but there’s no scientific proof. However, researchers believe that aloenin, a chemical compound in the plant, is a primary factor in promoting hair growth, as found in people with a hair-loss condition called alopecia.

Aloe vera contains vitamins A, C, and E. All three of these vitamins contribute to cell turnover, promoting healthy cell growth and shiny hair. Vitamin B12 and folic acid are also contained in aloe vera gel. Both of these components can keep your hair from falling out.

Aloe vera promotes healthy hair growth thanks to a special enzyme found in aloe called proteolytic enzymes. These enzymes effectively break down dead skin cells on the scalp that may clog hair follicles. If hair follicles are blocked with excess sebum, dirt, or dead skin, they won't be able to grow properly.
