We have between 100,000 and 150,000 hairs (up to 200,000 for red hair) implanted in our scalp.
Each one is made up of a root or hair bulb and a hair shaft, which is the hair itself.
Hair is essentially composed of keratin and melanin, the pigment that provides its natural colour. Hair growth occurs when bulb cells multiply and are pushed up, forming the shaft.
Therefore, it’s very important that the scalp - or in other words, the area where the bulb is implanted - is healthy and provides the nutritional elements needed to keep hair alive.
