Philip Kingsley PK4 Hair Protein Capsules, 800g

Special offer


Product information

Hair cells are the second fastest growing cells the body produces, however hair is also non-essential tissue, making it the last to benefit from absorbed nutrients. PK4 nutritional Soya Protein supplement contains the essential amino acids that hair is made of. As part of a balanced diet, PK4 helps to support the optimal growth of stronger & fuller strands. Hair grows in cycles which consist of three distinct stages: Anagen (active phase), Catagen (transitional phase) and Telogen (resting stage). The protein nutrients in the capsules are absorbed by the hair follicle during the Anagen phase of the growth cycle.

PK4 Hair should be taken in conjunction with a healthy diet. For best results take for a minimum of 3 months.
