  • Works like magic
This stuff works surprisingly well! I tested it out by putting some on my dry hair on my ends and up toward my crown, focusing on areas with fly-aways. Then I followed it with straightening my hair with a flat iron. It made my hair significantly less frizzy and sleek looking. Once straightened the product seems to hold my hair in place—like giving it a new set-point. Instead of looking like wavy hair that’s been straightened my hair just looked like it’s naturally straight. I really love that. It took little effort with my straightener and less passes to straighten it. It’s now part of my regular routine and will likely stay that way unless they stop making it. My hair is down to my waist, thick but fine, and naturally wavy. My scalp can get oily easily with products, but I didn’t notice any difference in oiliness while using this. The smell is not very noticeable. It’s like a non-offensive, clean smell. It doesn’t compete with my perfume. The consistency is like a watery gel. It almost feels like hair gel when you put it on because you can feel it dry to the hair quickly. But it doesn’t make it feel stif, crunchy, sticky, oily or anything. It feels kinda perfect, like magic. It’s a cool product, I love it and recommend it! ... show more

  • Healthy, soft hair. Helps with appearance of split ends
I love this product, I was recommended by my hair stylist and it helps with my dry ends due to balayage. It makes my hair smooth + silky and appears much better.

  • Makes your hair feel stronger
If your hair is a little damaged, this is a good product to use. It will help mend split ends due to over processing. I just use a small amount after I am done shampooing and conditioning my hair. You work it in to your hair especially getting it into the ends. It made it feel stronger and softer. I have curly hair so it reduced the frizz as well. Good product but overpriced! ... show more

  • Works well but overpriced
Like all their products this is way overpriced. Yes it works but not in the tiny amounts they suggest. If you have dry, processed long curls this helps but it takes a lot and it’s gets expensive.

  • FRIZZY HAIR? NO MORE!!!
This product is amazing. I needed something to put in my hair while it dries naturally to cut the frizz and tame it down. This product makes my hair frizz free, silky, soft etc. 10 out of 10 hands down. Best frizz control product on the market and totally worth EVERY penny paid!

  • Buy this
This was recommended to me for my fine hair as both a heat protectant and styling serum. I used it for the first time this morning and, so glad I listened. My hair is so shiny and soft. And, after using my L’ange duo to do waves in it, and I’m so happy with how much better they look!! I’ve received multiple compliments on my hair this morning at work, as well saying it looks so soft. ... show more

  • Immediate improvement in my dry hair
Highly recommended. Noticable difference after one use. My hair is more hydrated and has fewer knots, and yet the product is totally lightweight. Hair type is thin and fine, tends to get greasy quickly. Worth the price, lasts long
