Hair Type Wavy Hair
When I first tried this, I felt like it didn't do anything. This week in terrible humidity in the south I tried again and this time used a lot more all over my fine wavy hair and presto, it's amazing. I let it air dry and then sealed with kerasilk hairspray/humidity shield. Day 3 and I'm sitting here with great hair even after sweating the day before and no dry shampoo. Also, makes hair very shiny.
Holy Grail Hair Product!
The 5 star reviews aren't lying! I went out on a limb ordering this online and I have zero regrets! I used to use Redken United leave-in for years but always felt my hair was lacking, it felt dry and was frizzy. I decided to try something new. This hair product is gold. A little goes a long way, it detangles my hair and is so shiny and soft after styling. No more frizz! I'm so happy I found this product and I'll definitely be repurchasing!

Favorite new hair product!

I love the smell and feel of this product! It makes my hair feel so soft and smooth without weighing it down. I have fine straight hair and I don't feel flat when using this product. I also use it on my daughter as a detangler and it works great for that too.
The Perfect Everyday Leave-In with Heat Protection
Reviewed at
I've been using Nulastin's Leave-In Primer for a couple of weeks now and I'm really loving it so far! It feels super lightweight and smells amazing. I like that it doesn't leave my hair feeling greasy or heavy afterward, which is a big plus. I also really appreciate that it offers heat protection — it's nice knowing my hair is being protected while I style it. Overall, it's been a great addition to my hair routine!
