6 Leave-in Treatments for Your Softest, Strongest, Shiniest Hair

Whether you’ve given yourself one too many blowouts, dyed your hair more times than you can count or are just looking for a way to give your hair some extra shine, a leave-in hair treatment is the way to go. Not only will they make your hair softer and more reflective, some leave-ins can also strengthen strands and guard against heat damage. Below, find six of our favorites for every hair type.

Best Leave-in Treatment for Heat-Damaged Hair

Redken All Soft Moisture Restore Leave-in Treatment with Hyaluronic Acid

Hyaluronic acid is an amazing hydrator for the skin, but did you know its moisturizing benefits can be implemented in hair products, too? You can find the ingredient in this leave-in treatment from Redken, which strengthens and hydrates hair and helps it retain moisture for up to 72 hours. It helps tame frizz, smooth the look of split ends, detangles and provides heat protection at up to 450 degrees.

Best Leave-in Treatment for Frizzy Hair

Garnier Fructis Sleek & Shine Intensely Smooth Leave-in Conditioning Cream

If frizz is your main hair concern, we think you’ll love this green apple-scented pick from Garnier. It offers up to 72 hours of frizz control even in 97% humidity on straight, wavy and curly hair types. Come summer (or a tropical mid-winter getaway), it’ll be a must-have. 

Best Leave-in Treatment for Curls

L'Oréal Paris Dream Lengths Curls Leave-in Conditioner

Best for wavy to coily hair, this leave-in conditioner delivers major frizz control and shine without weighing curls down. Formulated with hyaluronic acid and castor oil, it leaves curls feeling soft, shiny and defined — like sleeping on a silk pillowcase. 

Best Leave-in Treatment for Color-Treated Hair

Kérastase Chroma Absolu Anti-Frizz Leave-in Treatment for Color-Treated Hair

A few spritzes of this leave-in conditioning spray leave hair untouchable in the face of frizz, humidity and heat damage. The formula’s antioxidant properties help keep your hair color looking fresh. 

Best Leave-in Treatment for Natural Hair

Carol’s Daughter Wash Day Delight Cream Serum Moisturizer

This lightweight curl cream detangles, fights frizz and leaves hair with a hydrated, silky slip for up to 24 hours. It’s packed with glycerin, which helps draw moisture into dry, dehydrated hair. It comes in two scents: delicate rosewater and fresh aloe. 

Best Leave-in Treatment for Fine Hair

shu uemura Izumi Tonic Strengthening Rice Water Treatment

Infused with Japanese-sourced rice water, this lightweight leave-in strengthens hair, adds shine and amps up volume. After just one use, it promises to leave strands up to 10 times stronger.
