I’d recommend using shampoo once a week, on a specific day. Make sure you wash your hair every day though with water, ensuring you get rid of all the dirt and smell effectively. Use johnsons’ baby shampoo on shampoo day but half an hour before your shower apply olive oil effectively into your scalp. Once you’ve finished washing it off (with water or water plus shampoo depending on the day) dry your hair with A TOWEL really well, then top up your hair/scalp with some more Olive Oil, maybe not as much massaging into your scalp as you’d do before a shower. Feel free to use boiling hot water on your body if you’ve gotten too used to it, which happens to a lot of people such as myself, but always, ALWAYS use cold water on your head. It’s really good for the scalp too. That’s it really. And eat your veggies 👍🏼
