Hair loss remedy. Parts of hair
Each strand of hair consists of three concentric layers, the cuticle, the cortex and the medulla. A proper hair loss remedy will address all three parts.
Cuticle
The outer layer is called the cuticle and is thin and colorless, its job is to protect the thicker cortex which contains the melanin.
Cortex
Cortex contains melanin. Melanin is responsible for the color of your hair and the actual color depends on what kind of melanin you have. There are two kinds, eumelanin which creates brown or black hair, and pheomelanin which makes hair appear red. Blonde hair is a result of very low amounts of melanin, the shade of the blonde again depends upon which type of melanin you have. Gray hair is a result of a lack of melanin which is often caused by age but can also be caused by stress and illness. A good hair loss remedy will especially care for the cortex.
Medulla
The innermost layer of hair is called the medulla and reflects light giving hair the various color tones it has. That's why hair color looks a lot different in sunlight than it does in the shade.
