Strengthen your hair from within Strong, healthy hair needs to be fed from the inside. Every single one of the 100, 000 – 400, 000 hairs found on an average head is made up of two parts: the root, which is nourished by blood via the papilla; & the hair shaft, which is visible, & largely made up of a protein called keratin. Pil-Food capsules provide the sulphurated amino acids (including DL-Methionine & L-Cysteine) the body uses as building blocks to encourage production of keratin, & to help hair keep its strength & elasticity. Keratin needs to be manufactured by our bodies as it is not something that can be rubbed in, or applied in some way to the hair shaft. How to take: 1 capsule, three times a day. This pack lasts 1 month. Recommended course is three months.
