Hair Care
Hair care is a term for parts of hygiene and cosmetology involving the hair. Hair care may include haircuts, where part of the hair is trimmed and hair dressing, where the Hair is combed and arranged. Hair care also includes hair washing, which is often done as part of a shower or bathing. Hair is often washed with specialized soaps called shampoos, and lost oils are replenished with hair conditioners.Shampoos are cleaning agents for scalp and hair shafts, if one has oily scalp a more detergent shampoo is needed. Conditioners and leave on products are for hair shaft protection and treatment, they are not supposed to get over the scalp as they leave more residue and increase dandruff.

Hair can be styled with the use of specialized combs or brushes and can be straightened with hair straighteners or curled with hair curlers or hair tongs.Hair is damaged much more easily when wet, so extra care must be taken.Scalp hair grows 0.33 cm per week on average and shampoos or vitamins have not been shown to noticeably to change this rate. The speed of hair growth varies based upon genetics, gender, age, and may be reduced by nutrient deficiency. The speed of hair growth also increases slightly when longer, due to the effects of gravity.Improper hair care can result in dandruff.
