Frequent trimming is the most important. Get the ends trimmed every 6-8 weeks to avoid getting split ends, which can halt hair growth. Nutrition is also important. A lack of nutrients can slow down hair growth. Taking a multi-vitamin supplement may help your hair grow faster.
Adequate sleep helps as well, since sleep helps regulate hormone levels.
The average person sheds up to 200 hairs a day. The hair is constantly replacing itself through most of a person's life. Shedding occurs at the fall-out stage, and prepares the follicle for the regrowth stage. If you feel your hair loss is abnormal or accelerated, consult a dermatologist or physician. Shampoo your hair with a clarifying shampoo.
