Hair

Introduction

Hair is a significant aspect of human appearance and identity. It is an extension of the body and is made up of keratin, a protein that is also found in nails and skin. Hair growth, color, and texture vary from person to person and are determined by various factors such as genetics, age, and environmental factors. This article aims to provide a comprehensive guide to hair, including its anatomy, growth cycle, care tips, and common problems.

Anatomy of hair

Hair is made up of two main parts: the follicle and the hair shaft. The follicle is the part of the hair that is embedded in the skin and contains the hair root and sebaceous gland. The hair shaft, on the other hand, is the visible part of the hair that grows out of the scalp. The hair shaft is made up of three layers: the medulla, cortex, and cuticle. The medulla is the innermost layer, the cortex is the middle layer, and the cuticle is the outermost layer.

Hair growth cycle

Hair goes through a growth cycle that includes three phases: anagen, catagen, and telogen. The anagen phase is the growth phase and can last up to seven years. The catagen phase is the transitional phase and lasts for two weeks. The telogen phase is the resting phase and lasts for three months. After the telogen phase, the hair falls out, and the growth cycle starts again.
