The changes which occur as we age, as well as an inadequate diet, stress, hair styling & lifestyle, can all have an impact on hair growth & the condition of our hair. The hair follicle is a highly active "factory". It has demanding metabolic requirements for oxygen, energy & specific nutrients which facilitate protein synthesis for hair growth & the production of scalp oils. This requirement for essential nutrients must be met to maintain healthy hair growth & the condition of the hair & scalp. Tricologic also provides other important nutrients involved in maintaining healthy hair growth & its condition including antioxidant vitamins C & E, betacarotene, iron, pantothenic acid, para-amino benzoic acid (PABA), selenium & vitamin B complex. As Tricologic is an orally administered supplement its benefits are delivered via the bloodstream directly to the hair root & dermal layers of the scalp where they are needed most.
