Great hair serum

Great for dry and damaged hair. Adds healthy shine and protects from heat. I use it on wet hair after shower for my curly hair and before ironing. It smells nice of fruity grape scent. Won’t be the last time I buy it. Arrived in good condition. Pretty affordable for an instant hair therapy product!

I'm impressed with how it really makes my hair sleek, not weighed down. I find the key is to make sure the hair is damp then add the product, then blow dry so the hair is very dry, and then follow with a flat iron. Its almost as good as smooth n' 'shine a product hard to find anymore.

Works great!

My hair is so dry that a simple conditioner has no effect on the frizz and dryness. Many products weigh my hair down and looks flat. This product does the job. I use a bit more than directed but it takes care of the dryness. Very light scent. It lasts a long time. Recommend if you have extra dry hair. I don't use a blow dryer. After shampooing I put it on dry hair.
