Thinning hair usually develops from hair loss over a prolonged period of time due to follicle shrinkage.
There are various factors resulting in follicle shrinkage; these includes:
• Hormonal imbalance
• Excessive oil secretion
• Poor blood circulation
• White blood cells attacking hair follicle
Follicle shrinkage eventually results in the suppression of the hair’s ability to grow thicker and healthier. In addition, the smaller follicles will have lesser capillaries attached to it, lowering the level of nutrition and oxygen reaching it in support of the mitosis (cell division) process.
