The few simple techniques one should keep in mind while washing one's hair include:
Soak to the Core: Ensure that your hair is soaking wet before applying shampoo. This will help shampoo move through your hair more easily and do its job effectively.
At Medium Heat: Use water which is at a medium temperature. Water that is too hot could dehydrate your hair.
Massage into scalp: Use your fingertips to circulate the shampoo into your scalp with gentle massaging movements. This will help eliminate dirt, while increasing blood-flow to your scalp and promoting healthier hair growth.
Rinse off Thoroughly: Always rinse off the shampoo completely. Shampoo build-up can dry out your scalp. You can use a clarifying shampoo once a month to eliminate shampoo build-up.
Repeat if Required: Repeat the process again if your hair is very dirty or greasy. Avoid shampooing more than required as it will dry out your scalp and hair.
Condition Appropriately: Don't use too much conditioner and only condition the lengths and ends of hair. You can use a wide-toothed comb to spread the conditioner evenly through your hair.
Rinse with Cold Water: End with a cold water rinse. This helps lend a shine to your cuticles.
