Hair is a derivative of the epidermis and consists of two distinct parts: the follicle and the hair shaft. The follicle is the essential unit for the generation of hair. The hair shaft consists of a cortex and cuticle cells, and a medulla for some types of hairs. Hair follicle has a continuous growth and rest sequence named hair cycle. The duration of growth and rest cycles is coordinated by many endocrine, vascular and neural stimuli and depends not only on localization of the hair but also on various factors, like age and nutritional habits.

Hair development is a continuous cyclic process and all mature follicles go through a growth cycle consisting of growth (anagen), regression (catagen), rest (telogen) and shedding (exogen) phases. The duration of the phases changes based on the location of the hair and also personal nutritional and hormonal status and age. Another main factor that affects hair development is the products used.

Research has shown that various chemicals lurking inside shampoo may induce serious health risks, like memory loss, eye and skin irritation, hair follicle damage that can lead to hair loss.

Some shampoo use the lathering agents, emulsifiers and synthetic fragrances that contain hundreds of harmful chemicals.
Some of the additives to avoid in conventional shampoos:

  • Propylene glycol, known as the main ingredient in antifreeze, is also found in makeup, toothpaste and in your shampoo. It can cause allergic reactions.
  • Sodium lauryl sulfate and ammonium lauryl sulfate are common causes of eye irritation. They can also damage hair follicles. When absorbed into the body from continuous contact, they can bring on asthma attacks.
  • Synthetic fragrances contain hundreds of chemicals, some of which have been known to cause headaches, dizziness, rash, hyper pigmentation, coughing and vomiting.
