Deal With Itchy Scalp
First and foremost you need to understand that itchy scalp is caused due to unclean/unhygienic maintenance of hair and that show you are not taking care of your health and your hair so you need to start with washing your hair every other day, but make sure you are not using any antidandruff shampoo, they are not for you, I am not saying that they are not good, I am just saying that they are not for you, you know what I mean though, use the mildest shampoo you know and if you don’t know any good shampoo then use baby no tear shampoo am they are best.
Stop using chemical, hair dyes, and any other chemical that can harm your hair and scalp and that will help your itchy scalp too, and you need to understand that if you are getting itchy in your skin then your skin need moistures so use all those mask that has moistures in them, you can use any essential oils for that, but the best one is olive oil, mustard oil and almond oil and if you mix yogurt with this then this is the best mask for your hair.
Never use worm water to clean your hair, that will wash your natural oils too and always apply some hair massage with any essential oil prior to hair wash, and if you really want to have marvelous hair and healthy scalp then try to apply yogurt and mustard before every hair wash
Drink lots of water and maintain a healthy and balanced diet.
