This serum is like the holy grail for my hair. It stays silky smooth for days whenever I use this serum, even through exercising and sweating.
For a polished hair look, this product is my go-to. And if you plan on reaching for those hair tools anytime soon, here’s why you need to try it.
Design Essentials Silk Thermal Strengthening Serum, $23.99

Whether you have relaxed or natural hair, this Silk Thermal Strengthening Serum works like a charm. I love to add a pump or two of this serum to my hair before curling or straightening it, and it gives my hair a definition and shine like no other.
The formula in this serum is gentle, lightweight and versatile enough to be used on all hair types. It’s infused with amino acids that strengthen the hair. The texture is silky smooth so you can run it through each strand, and it even helps protect your hair from heat damage.
Amazon reviewers praise this serum as a must-have product for those who regularly apply heat to their hair. “If I could give 20 stars, I would. This product smells so good and it is lightweight without feeling greasy,” says one reviewer. “My hair is natural, but I keep it straight with flat iron, and this product gave me a shine and straightened it like a relaxer was in. I highly recommend.”
