Wash your hair with a mild-formula shampoo and do it at least once per week. If you go too long between washings, oil and skin cells build up and cause dandruff. Look for a shampoo specially formulated to fight dandruff. Focus on lathering the shampoo around the roots of your hair, and leave it on for at least five minutes so it has time to work.
Condition your hair after shampooing. Shampoo strips your hair of its natural oils and conditioner basically works the opposite way. It moisturizes your hair, replenishing it and keeping it hydrated and healthy. Don't overdo it with the stuff; put a bit of product into the palm of one hand and work it into your hair from the ends up. Don't condition around the roots of your hair -- this will only leave your hair oily and limp.
Apply a hot oil treatment about twice per month, massaging the oil into your scalp. Cover your head with a plastic cap and let the treatment do its magic for 15 to 20 minutes before you rinse it out with lukewarm water and follow up with a shampoo.
Use a natural-bristle brush to detangle your hair. This pulls out any flakes on your scalp and is generally easier and less damaging on your hair. It also helps by stimulating blood flow to your scalp, to stimulate natural oil production and, in turn, help get rid of that annoying dandruff.
Give your -- albeit favorite -- hairstyling products a break. You know that hair spray, hair gel and hair wax you love? Well, all these products create buildup on hair, often resulting in flakes. It'll be tough, but your hair will thank you, and you won't have flakes falling on your shoulder on your hot date tonight.
After using the same shampoo for a while, your hair may start to get used to it and when that happens, the effects may start to wear off. It helps to alternate between shampoos, so switch it up every couple of weeks to prevent this from being an issue.
If you try different measures and don't see any difference, it may help to speak to a dermatologist. She can evaluate your dandruff problem and determine if a health condition is at play.
If your thick hair is styled in cornrows or dreadlocks, use your fingertips to massage your scalp and stimulate blood flow instead of a brush.
