In human hair grow in cycles which last up to six years. When DHT levels are high, hair follicles may shrink and growth cycle gets shorter which results in hair loss and thinning. Blockage of 5-alpha reductase enzyme inhibits DHT adherence to scalp and helps to avoid hair loss and thinning. Inhibition of 5-alpha reductase enzyme is the mechanism employed in the medicine Finasteride in order to protect from hair loss. Substances present in Pumpkin seed oil have the same mechanism of action and significantly help in case of alopecia areata in men. Maximum effect is reached when pumpkin seed oil is used together with other DHT blockers, which are carefully selected in our ingredients.
