Anti-androgenic Saw Palmetto regulates levels of DHT in the body, by blocking the enzyme 5-alpha-reductase, which is responsible for the formation of DHT and as a result of being exposed to it, damaged hair follicles. Clinical studies show that nettles inhibit 5-alpha-reductase, the enzyme which converts testosterone to DHT. Rich in vitamins A and C, minerals and amino acids, nettles stimulate the circulation of the scalp. Extract of rosemary increases circulation, cleanses the scalp and stimulates the hair root, while also helping to remove any impurities and tackling dandruff and oily roots. Fenugreek, a herb used in medicine for centuries, promotes healthy hair growth. Zinc also promotes healthy hair growth, as hair loss can be a sign of zinc deficiency. Hair can be a great indicator of health and well-being but harmful treatments, lifestyle stress, hormonal imbalances, dietary deficiencies and genetic factors can all take their toll resulting in weak, lacklustre locks and thinning hair. Backed by the results of clinical studies trichologen brings together a selection of natural ingredients known for their hair generating properties. trichologen gets to the root of the problem by stimulating circulation of blood to the scalp to fire-up follicles and fight hair loss and tackle the causes of dandruff and greasy hair.
