If your hair tends to be oily, try a dry shampoo to help keep your scalp feeling fresh between washes.
Using apple cider vinegar when you rinse your hair can also help seal the cuticle and make your hair shiny. Mix 1 part vinegar to 3 parts water in a spray bottle, apply to your hair, and massage from your scalp to your ends. Let it sit for 5-10 minutes, rinse, and follow with your favorite conditioner. Use this treatment not oftener than once a week.
If you have a hooded dryer, you can apply the treatment to your hair and put a shower cap over your hair. Sit under the dryer for 15 minutes for a quick treatment.
If you use a hair dryer, turn it on to a lower temperature setting. This works especially well for finer hair types.
