Shampoo for straight hair: how do they work?
Straight hair shampoos work differently than other types of shampoos. In general, these products contain ingredients that reduce the surface tension of the hair, which means that individual strands of hair move apart from each other. This makes it harder for your hair to curl and create waves. Many shampoos for straight hair also contain silicones or polymers that form a protective coating on the hair, thus reducing the risk of hair damage or breakage.
Straight hair shampoos are often formulated with delicate surfactants which do not remove natural oils from the scalp and hair. This is important because straight hair tends to need more hydration than curly or wavy hair. Straight hair shampoos may also contain ingredients such as protein and keratin, which help strengthen hair and prevent breakage.

A lot depends on the health of your hair, your styling routine and the type of tools you use (such as a hairdryer or straightener). Additionally, the way you apply the shampoo can make a difference: it's important to gently massage the shampoo into your scalp, avoiding rubbing too vigorously. The lengths should always be washed last, simply letting the foam fall onto it and massaging it gently, without rubbing.

If you have fine or oily hair, for example, you may want to look for a lightweight shampoo that won't weigh your hair down.

If you want to keep your hair smooth and shiny, however, you could opt for a shampoo with keratin or hydrating oils such as coconut oil.
