Review: Excellent product!!! - My hair is a bit coarse, porous, and dry. I use this product after washing, when my hair is towel dried. I think it helps protect it from the blow dryer. After my hair is dried, I use it at least two more times about eight hours apart to add moisture. It helps my hair feel soft, silky and leaves it looking so healthy! On top of that, it smells so Good! I highly recommend it for anyone with dry, coarse hair.
Review: Excellent product - I am very happy with this product!!! I have naturally thinning curly/ wavy hair that is prone to frizzing and this product has been amazing!! My hair looks healthy and young again. My doctor uses the vitamins offered by this company and he had pulled it up on his PC to recommend it to me during one of my appointments. I purchased both the vitamins and the hair serum and couldn’t be happier with both. No more bad hair days! Why did you pick this product vs others?: Recommend to me by my primary care physician when I complained of my hair thinning and dying out due to medication & aging ( I’m in my 50’s) Hair softness: this product makes my hair very soft and shiny but helps control frizz Value for money: definitely worth buying. I bought 2 bottles on sale. It was a buy one get 1/2 off one so it was worth the price paid. Greasiness: Non greasy Longevity: last until next wash. I apply a little on dry hair each day in between washes.

### ⭐⭐⭐⭐ Best thing for my frizzy hair In and extremely dry climate
*by T***E on October 28, 2025*

Wonderful scent, if you use too much it can feel a touch greasy but only if uou use to much. This definitely helps to detangle my hair but you can tell that's not it's main purpose. What it does help with the most is helping with my severe frizz problem. As someone who has fine hair and A LOT of it, this helps my hair to shine without being too oily as long as I don't use too much. Try not to get it on the handle of your brush though. My only complaint is that it can be a lil bit thick and for my shoulder length hair the instructions say to use about the size of a cherry which I actually found not quite right. I had to use this for about a week to figure out the right amount for my hair (which I guess can be expected as everyone's hair is different). Either way I will be buying this again as living in such a desert as I do; the static can get so bad here that my hair can often frizz to nightmarish levels. Definitely worth the money as far as I'm concerned even though I would prefer a little bit more product for the money.
