Mend Heat Protectant Leave-In

Heat Protectant | Smooths Split Ends | Repairs Damage

A nourishing leave-in conditioner formulated to repair damage, reduce breakage, and smooth split ends. Heat protection up to 450°F for stronger, more resilient hair.

WHAT IS IT?

 

Mend shields hair from heat while improving the look of damage. A vegan collagen peptide and omega-3–rich chia seed oil reinforce fragile ends, seal the cuticle, and smooth frizz. Provides heat protection up to 450°F. Lightweight, non-greasy finish that won’t weigh down fine hair. Color-safe, dermatologist-tested and hypoallergenic.

Heads up: Mend isn’t applied to the scalp, so it does not work to slow or repigment greys. For pigment support, pair with Not Today, Grey, our daily supplement, plus a topical treatment like To The Root® Scalp Serum or Wash Shampoo.

100% natural cedar + sage fragrance; made without sulfates, parabens, phthalates, synthetic fragrance, PEG, formaldehyde, or dyes.

HOW TO USE

 

1. Apply to damp hair after towel drying.
2. Focus on mid-shaft to ends.
3. For thinner hair, use a dime-sized amount; for thicker hair, use a quarter-sized amount.
4. Comb through to distribute evenly.

CLINICAL RESULTS

 

45% less hair breakage vs. untreated hair
Heat protection up to 450°F, maintained even after multiple passes

Based on a 3rd party clinical study, simulating repeated grooming on hair exposed to flat iron heat at 450°F. Individual results may vary.

    Panthenol helps to lock in moisture and smooth the cuticle from the inside out, decreasing tangles for all hair types.

  • Protect

    Chia seed extract and a blend of proprietary ingredients prevent damage from heat exposure up to 450°F.

Clinically Proven to Protect Hair from Heat and Breakage

Proven in a lab to reduce breakage and preserve hair strength under extreme heat conditions.

    Great as a straightening cream

    I put this in after I wash and condition my hair. After I let it air dry and then straighten with a flat iron, it works great. No more flyaways!

FAQs

It’s easy to add Mend into your hair care routine. Just follow these steps:

  • Step 1 – Apply a dime size amount of Mend to damp, towel-dried hair.
  • Step 2 – Work Mend through your hair from the mid-length to the ends —you can use a wide-tooth comb to disperse it evenly.
  • Step 3 – Safely heat-style up to 450ºF (which is higher than the temperature of most heat-styling tools!)
  • For curly hair, you can scrunch for texture. If your hair is very fine, you'll need to use less product for the same smoothing and hydrating results.

No, Mend will not weigh your hair down. The ingredients we use in Mend are lightweight and are easily absorbed so it shouldn't weigh down even the finest hair.

Mend delivers vegan collagen (sr hydrozoan polypeptide) that is quickly absorbed deep into your hair strand. This seals and smoothes your hair cuticle so that it’s stronger and more resistant to damage from heat. Mend hydrates and nourishes your hair with moisturizing ingredients that protect, hydrate, condition, and boost your hair growth. Jojoba seed oil strengthens your hair and our blend of esters (lightweight conditioning oils) works to reduce the appearance of split ends. Mend allows you to break the cycle of repeat hair damage from heat-styling. Because Mend coats each hair strand with lightweight heat protecting ingredients, each styling session becomes less damaging to your hair. While Mend protects your hair up to 450ºF (which is higher than the temperature of most heat-styling tools), we recommend using the lower heat settings on your styling tools — especially if you have fine hair.

The outer layer of your hair strands (the cuticle) is covered in layers of scales like a snakeskin. In healthy, hydrated hair, the cuticle layers all lay flat. This means smooth, shiny hair that doesn’t tangle or frizz. Heat-styling opens up the cuticle scales and leaves your hair vulnerable to breakage, split ends and tangles. Mend works by creating a lightweight barrier around each hair strand to keep the cuticle smooth and protected from heat damage. Every time you use Mend, it seals your hair cuticle to prevent future hair heat damage. Because Mend delivers collagen to your strands, it also helps to reduce the appearance of split ends. Mend protects your hair from heat damage up to 450ºF (which is higher than the temperature of most heat-styling tools!). Our clinical tests show that it also reduces hair breakage by 45%.

Live In Mist® is a lightweight leave-in conditioner mist that helps to detangle hair, restyle dry hair, and protect from UV exposure. Mend is a vegan collagen leave-in conditioner cream that nourishes hair, helps the appearance of split ends, and protects hair from heat damage and styling stress.

Yes, Mend utilizes a vegan collagen that is safe to be used daily and continually. Some deep conditioning leave in treatments leave proteins that can build up on the hair over time, causing it to become brittle. Mend is formulated to add elasticity and flexibility to the hair strand and protects against heat and styling stress.
