Why use Smart Sleek Leave-In Conditioner?
Ideal for progressively straightening hair, sealing split ends, reducing frizz
and hair volume. It's a perfect complement to protect hair from high temperatures like flat irons and hair dryers creating a
barrier to protective layer that prevents hair from burning, retaining moisture, and
controlling frizz.
Recommended for people that want straight hair.
