Effect of water temperature on the scalp and hair?

Scalp

* Hot water can dry out the scalp and cause itching, flaking, and dandruff. This is because hot water strips away the scalp's natural oils, which help to keep it moisturized.

* Cold water can help to soothe the scalp and reduce inflammation. It can also help to close the hair cuticle, which can help to prevent damage and keep hair looking healthy.

Hair

* Hot water can damage hair by causing the cuticle to lift. This can make hair look frizzy and dry, and it can also make it more susceptible to breakage.

* Cold water can help to seal the hair cuticle and prevent damage. It can also help to add shine and body to hair.

Overall, it is best to use lukewarm water when washing your hair and scalp. This will help to avoid the negative effects of both hot and cold water.

Here are some additional tips for healthy hair and scalp:

* Use a gentle shampoo and conditioner. Avoid using harsh products that can strip away the scalp's natural oils.

* Condition your hair regularly. This will help to keep it moisturized and prevent damage.

* Avoid using hot tools on your hair. If you do use hot tools, be sure to use a heat protectant spray to help protect your hair from damage.

* Get regular trims. This will help to remove any split ends, which can make hair look frizzy and dry.

* Eat a healthy diet. Eating a healthy diet that includes plenty of fruits, vegetables, and whole grains can help to promote healthy hair and scalp.

* Drink plenty of water. Drinking plenty of water can help to keep your hair and scalp hydrated.
