Oleanolic acid is extracted from olive leaves. This component has the ability to inhibit 5-alpha-reductase, the enzyme that acts on the hormone DHT to accelerate and shorten the hair cycle.

This hormone is responsible for follicle atrophy and excess sebaceous secretion. Oleanolic acid acts directly on the enzyme, stimulating hair growth and lengthening the anagen phase of the hair cycle.

The K.THERAPY ACTIVE product line contains olive leaf extract, which regulates the activity of the sebaceous glands, reduces the production of DHT and manages to normalize sebaceous secretion from the scalp.
