 Density:

 The density of hair depends on the amount of hair as more hair more the density.

 Hair Structure:

 The thickness of the strands of the hair depends on hair structure. Different types of hair are:

• Fine

• Medium

• Coarse

 Porosity:

 The capacity of a person's hair to absorb moisture is determined by hair porosity. The amount of tears or gaps in the cuticle layer determines how porous hair is. The outside layer of the hair, known as the cuticle, shields it from damage.

However, chemically or bleach-damaged hair is more porous than hair that hasn't been treated.

You should avoid strong chemicals ad high-heat treatments to let the hair recover.

 General Hair Care Tips:

You can try the following tips for hair care

• Shampoo: Always concentrate on the shampoo before use. Use shampoo as often as u need it. As everyone is having different types of scalp and hair so shampoo will be used more often on oily hair.

• Condition: Use concentrated conditioner on the tips of the hair. A person should use a conditioner after each shampoo.

• Dry: People can either use a blow dryer or wrap the hair in a towel or can air dry the hair. Natural drying can cause less damage than blow drying, but according to the research using a blow dryer at a distance of 15 centimeters and moving continually can cause less damage.
