It is recommended that the hair should be shampooed at least once a week, to help remove residual styling products, normal dead skin cells, etc. Your hair may need more frequent shampooing depending on your activities like aerobics. swimming, or other outdoor exercise due to perspiration, pollen, dirt, etc….. However, be cautious not to shampoo too often, or use “hard water” with high mineral levels, because you could strip hair of natural oils which can cause hair & scalp dryness.
Deep condition at least once a month. Gently shampoo your hair, and apply the deep conditioner so it completely saturates hair from scalp to ends. Leave on for 15-20 minutes under a thin plastic or thermal “heat cap”, to permit conditioners to penetrate scalp and deep in the hair shaft. Rinse well and style as desired.
Deep conditioning provides more intense strengthening and moisturization, helps “restore” some natural oils and, and can help eliminate dry & brittle hair. Deep conditioning can also enhance your hair’s luster (sheen) and body.
By using an anti-dandruff shampoo you can get rid of dandruff, otherwise you can also use a mild exfoliant to get rid of it. You can use an easily available exfoliant, baking soda to remove the dead skin cells and also to balance pH levels on the scalp. Using baking soda will reduce the growth of fungi that cause dandruff. Simply wet your hair and rub a handful of baking soda onto the scalp. Wash it off with warm water. You can also mix baking soda in your regular shampoo and then use it.
To maintain long hair you need to take care of them properly. Just washing and shampooing your hair is not enough to keep them healthy. You need to schedule regular trims to keep them in healthy state, also shampoo and condition them as per your hair type and dry them with care. Avoid tight hairstyles that might pull and damage the hair shaft. What you eat also matters, so have a balanced diet to keep your hair long and strong.
