What It Does
This conditioning heat protectant fortifies hair at the deepest level, preventing heat damage, dryness + breakage from blow drying and hot tools.
• Delivers heat protection at the core*, with patented resilicore™ heat-shielding technology to prevent heat damage up to 450°F (232°C)
• Protects against damage from heat, mechanical and environmental aggressors such as UV rays
• Lightweight moisture + hydration enhances smoothness and softness; hair feels and looks healthier without being weighed down

What Else You Need to Know
Heat protection from cuticle to the cortex*: resilicore™ heat-shielding technology is a breakthrough innovation inspired by resilin—a natural protein that can withstand extreme temperatures. Unlike traditional heat protectants that stop at hair's cuticle, resilicore™'s size + molecular makeup allows it to penetrate deep into the cortex, forming a protective shield that fortifies from within. This targeted protection delivers extended defense where hair needs it most.
Weightless conditioning: Lightweight cream transforms into a spray + binds to hair to help regulate lasting moisture balance, detangle, smooth for more manageable hair. pH-balanced formula minimizes cuticle swelling for less frizz, and more shine.
Created for all hair types + textures. Can be used on extensions.

Apply throughout sectioned hair, brushing through to help with even distribution. Less is more. Start small and build as needed. Hair should feel soft and tangle-free but not coated. Use on towel-dried hair before blow drying and on dry hair before hot tools.

The other heat protectant I before was obviously bad for my hair so I needed a huge upgrade and the k18 did exactly that

Protects hair like nothing else!
I can see a real difference using this vs other heat protectants. Only downside, is the conditioning agents are slightly heavy for fine hair.
