There is certainly ample scientific evidence that G.H3 may help recolor and regrow hair (47,48,49) Once again, the pharmacological action is not clearly understood. It is known that endocrine imbalances reduced circulation can lead to the weakening and thinning of hair. Poor nutrition or nutrition inadequately communicated to the scalp may result in poor hair quality.

As already documented, G.H.3 reportedly helps restore endocrine balance. It improves circulation to all parts of the body through vasodilatation. PABA also is believed effective in improving hair quality (50) The ionised and stabilised nature of G.H.3 may allow the PABA to perform even more effectively.

The regrowing and recoloring of hair does not occur at all in some people. Even when it does, several years may pass before appreciable results are obtained. Nutrient or endocrine deficiencies may not be the cause in some instances of poor hair quality or hair loss. In these cases the product may not help.
