Whether you’ve got chaotic curls or textured waves, you can probably relate to the feeling of coveting smooth, frizz-free strands. But before you reach for your heat tools, you should know there’s another option out there: hair straightening shampoo.

Straightening shampoos are packed with powerful ingredients like keratin and shea butter that leave your locks silky-smooth. And while these products won’t magically change the texture of your hair, they’re super effective at taming frizziness and unruliness even during the most humid of days so that styling your strands (whether you opt to air dry or blow them out) is a much more manageable task.

If your interest is piqued, there’s more to get excited about because we’ve curated a list of the 10 best hair straightening shampoos around—plus, a few details about what makes a straightening shampoo truly effective and worth buying.

What Makes An Effective Straightening Shampoo

When shopping for a straightening shampoo, you'll want to take a look at the ingredients list. Straightening shampoos are known to contain a high level of conditioning agents like silicones and polymers. These agents are water-resistant, which prevents your strands from absorbing moisture and curling back into their natural state. As mentioned before, straightening shampoos also have potent and reparative ingredients such as keratin and shea butter to nourish the scalp and strengthen weak strands all while giving it a silky smooth finish.

How We Found The Best Hair Straightening Shampoos

It’s a tedious task to comb through user reviews and best-seller lists, which is why we put our ranking algorithm on the job. Unique to Rank & Style, this tool uses data to find and grade products so that you can have a better shopping experience. Ahead, find out which shampoos made the cut, from salon-approved brands like R+Co and Moroccanoil to niche cult favorites like Sol De Janeiro and Davines.
