Every girl with rebellious hair will tell you that the secret to getting sleek, frizz-free locks is putting in lots and lots of work and dealing with lots and lots of damage. From frying our strands with hair straighteners to getting those on-trend straightening perms, our tresses go through some major havoc trying to achieve ultimate sleekness. Plus, the time and effort involved can be exhausting—an at-home blowout can certainly feel like forever. The struggle is even more real in the summer with heat and humidity becoming an added (and stressful) factor. Unruly hair can be demanding—it may take an insane amount of product to keep it tame, but by the end of the day, you find yourself back at square one again. Not ideal, right? The solution is finding a product that suits your specific hair type and encourages the strength of your hair.

When searching for the right straightening product, look for formulas that not only effectively and gently smooth hair, but also provide benefits like softness and shine. It’s also crucial that the formula protects hair from any heat damage caused by blow dryers, hair straighteners, and even the harmful rays of the sun. What’s key here is protection and strength—the longevity of your hair is extremely important. You want to make sure your hair can withstand everyday styling, no matter how extensive. Healthy hair is beautiful hair.

Here, the perfect list of the top hair-straightening products to solve your woes.

Infused with shea butter, the formula not only smooths misbehaving hair, but seals the cuticle to keep it smooth throughout the day. It also protects strands from severe heat—up to 450 degrees—making it an ideal product for those who like to heat style their hair. It is also intensely moisturizing, giving thirsty hair much-needed hydration. When blow drying, aim the dryer above each section, towards the floor, to really tightly seal the cuticle for a frizz-free and shiny finish. Give each section a cool shot to really lock in the style.
