Best Hair Straightening Shampoo Buying Guide


People often think that while buying shampoos, we have to think about our hair type. The truth is that, along with hair type, we may also know what our scalp type is. For example, if the scalp is oily, but the hair is dry, go for a cleansing shampoo for the scalp and a conditioner for hair.

Hair Type:

If you have dry hair, buy moisturizing shampoos. For thin hair, prefer using diluted mild shampoos or shampoos specifically designed for hair fall rescue. 

PH Level:

Scalps have a higher pH value than hair. For dry hair, shampoos with lower pH values are best suited so they can moisturize the hair. You can even use shampoos with the same pH value as your scalp and hair, which usually is 5.5. If you use hair straightener shampoo with a higher pH value, they will become weak and rough because hair cuticles lose their strength. If you lose shampoos with a lower pH value, it will result in shiny, smooth, and straighter hair.


It is best to buy sulfate-free shampoos so you do have to feel any irritation on the scalp. It will also protect your hair from hair loss and will boost its growth. You will have a clean dandruff-free scalp.
