Best Hair Smoothing Serum

Serums are a great way to achieve silky, smooth, static-free hair and you only need a dime-sized amount every time you use it so these products can last a long time. Almost everyone can benefit from using a hair serum, no matter if you have straight, curly, coarse or fine.  However, oily hair types might not benefit because serum can easily complicate already-oily hair.

These five hair serums were chosen because they help make your hair healthier overall thanks to ingredients like algae extract and vitamin E, protect from heated styling tools with ingredients like hydrolyzed wheat protein, and smooth away frizz with silk polymers and silicone.

John Frieda Frizz-Ease Hair Serum Extra Strength

This award-winning formula offers up the brand’s highest concentration of frizz fighting ingredients which includes hydrolyzed silk proteins, algae extrace and mineral oil to tame and smooth tough, coarse hair, so it’s ideal for those who have trouble keeping their texture in control.

Along with Dimethiconol which smoothes and adds shine, there’s smoothing seaweed extract, and ethylhexyl methoxycinnamate which repels humidity and protects against heat/UV rays. John Frieda is known for some of the best frizz-fighting products around and for years I’ve used their creams and styling products for my own curly, fine hair.

TIGI Bed Head Glaze Haze Semi-Sweet Smoothing Unisex Hair Serum

Part of the playful Bed Head Candy Fixation line, this semi-sweet smoothing serum coats every strand with an anti-humidity formula that adds shine and softens hair texture; it also speeds up drying time when applied to wet or damp hair.

The ultra-nourishing formula is lightweight and improves the health of your hair overtime with rice bran oil which adds protein to strengthen hair and smooth the cuticle. There’s also bamboo extract to prevent breakage and splitting, cashmere keratin which provides restorative proteins for conditioning, and sugar cane extract that leaves a scented aura of creme brulee wherever you go.

Matrix Biolage Thermal Active Repair Gloss

Formulated to work best on damp hair, this is an extremely lightweight, paraben-free serum. It provides protection against even the highest temperatures with a thermal protectant, while also formulated with rich nutrients like vitamin E, antioxidants and fatty acids.

Matrix is one of the most popular professional hair care brands because it’s ultra-nourishing, reliable and affordable. With a hold of level 1, you can be rest assured your hair won’t feel sticky, rough or stiff.

The Body Shop Grapeseed Glossing Serum

The Body Shop is known for having a great array of beauty products professionals swear by and this serum is no different. It works wonders for those with extremely dry hair because of the rich sesame, jojoba, and grape seed oils, which restore shine and softness, banishes flyaways, and smoothes hair cuticles.

For those who love heated tools like blow dryers or flat irons, this serum guards against damage with a thermal protectant and you can also use it on wet or dry hair. This product smells fresh with a touch of lemon oil as well as being free of sulfates and parabens.

Marc Anthony Style Straight Secret Silk Frizz Away Serum

Marc Anthony is also a trusted, award-winning hair care/styling brand. This serum makes hair feel silky, with smoothing silicone and hydrolyzed silk fibers while the formula is so light, it won’t weigh your hair down.
