This product saved me ...

Quick Take: easy to use, quick results
I have never had an itchy scalp before this past winter. And whether it was due to the weather (haha) or medication that I had been on, I was going crazy. I received a sample of this from my Sephora store and although I was hesitant to put something on my hair overnight, I was desperate. By night two the itching had subsided and by night three, I had purchased my first bottle. First I must say it dries very quickly and does not stain my pillowcases, nor does my hubby even notice that it is in my hair. Second, my fine curly hair is chemically straightened and is colored and highlighted. I think that I am now starting to notice new hair growth since using this product.--as another reviewer mentioned. I thought it was breakage due to all of the chemical treatments, but had been assured by both of my hair dressers that indeed it was new hair coming in. Who can complain about that? So I guess, bottle number two will be on its way! Just a little side note: I probably use too much product and I rarely heat style my hair because I am blow dryer challenged. I'm not sure if this matters to anyone, but I just thought I should mention it.

Great but not enough product
-04.18.13
Quick Take: easy to use, quick results, amazing, natural, expensive, vitamin riched
This is something I think everyone should try, however you should buy a least two bottles to have enough to cover your entire scalp every night for two weeks, which can get very pricey.
Overall the product is amazing, its a natural vitamin cocktail that your hair will just eat up, it also feels very fresh feeling on the scalp. Doesn't smell really at all.

So Glad I Tried It!
-03.23.13
I had dry, flakey scalp & tried using a bunch of dandruff products. The more I used them, the more my scalp itched. I ended up using them too much and they burnt my scalp. I had hair loss & burning, itching scalp. Now I need to be careful not to use any product with alcohol in it or it'll burn and cause hairloss. I've been wanting a Biotin scalp treatment, but they all had alcohol, until I found this one. I love this product! It is so soothing to the scalp and helps the itch. Makes your hair soft and it smells light and clean. My hair looks shinier and is coming in fuller. I wont be without it now!

Quick Take: easy to use, quick results
I color my hair a lot and I started to feel as though my hair was thinning and breaking easily. Although I would consider my hair to be in good condition, I was looking for something to give it that extra thickness and shine that I used to have when I was younger. I am always looking for the best deal and I was hesitant to spend so much on a product that i did not know much about. I am SO happy that i did! I noticed the product working the first week. It is so easy to apply on your scalp before bed and it seems to soak right in and not feel greasy. You will definitely need to wash your hair the next day after you apply but I have found that I do not need to put in every night to still get the same results!

Review 6 for Biotin Lightweight Reparative Hair Serum

It works!
-02.05.13
I have had issues with my hair over the past year due to stress and depression. I've been trying anything I could get my hands on to try and help. Any stylist and/or doctor will tell you biotin is good for hair (and nails), so I gave this a try and I'm so glad I did. I've noticed a huge change in my hair after I started using this. I use it at night, before bed (a whole dropper full) and massage in to my scalp, and use a little more on my ends. In the morning after I shampoo, I use a much smaller amount directly on my scalp and ends (two to thee drops for each area). I've noticed a lot of "baby" hairs under my bangs (it's regrowing!!) and my hair feels amazing.
Please Note: My hair was thinning due to stress. I'd had labs done to check for any medical reasons behind my hair thinning and all of my results came back great. If you have thyroid issues or alopecia, I can't say if this would work for you.

Good Product in Tandem with the Rest of the Series
-12.26.12
Quick Take: easy to use, quick results
This is a fantastic product, it makes my scalp feel good and my hair very shiny. Typically I use it at night and when it is rinsed out in the morning, my scalp feels fabulous (I've noticed a reduction of dry skin) and my hair is slightly thicker (it is fine). Otherwise I will on occasion mix this into the Bay Leaf treatment to enhance its effects. It's a wonderful product, but not necessarily a must have.

Give it time - it's amazing
-12.09.12
Quick Take: easy to use, helps scalp, stops breakage, rejuvenates damaged hair, nice scent, hair is shinier bouncier
After using for 3 months I started to notice thicker, fuller, longer hair. The biggest difference is less tangling and breakage, and my ends are curly instead of straw-like frizz! My scalp, which is prone to dryness, sores, and itching, is in perfect condition. This initially is a costly purchase, but it will last at least six months. A little goes a very long way and you use only a couple of drops at night. If you have breakage problems this is truly worth a try.

Protects ends from breaking
-10.21.12
It's been very very dry in my neck of the woods lately, and my already dry hair has been tangled and coarse. Sometimes I see tiny pieces of hair fall in my sink when I'm washing my hands, because my hair ends break so easily, even if I just "fluff" my hair. I have been using this serum as a "sealer", mostly on the ends of my hair. I'm about half way through the bottle. When this is on my hair, I definitely see less breakage, and my super dry ends get a soft, springy feeling. I don't have any scalp problems except occasional itchiness from dry skin, but I have put this on my scalp to see if it would do anything. It soothes any itch, and it feels slightly cooling. This serum does nothing to detangle hair, so I can use it only when I plan to do a wash or thorough-rinse out on soaking wet hair. I think this serum is probably meant for fine, thin hair and I have medium-thick, coarse, curly hair. I need to use waaaay too much just to cover my hair for this to be cost-effective. Bottom line is that it truly seems to help keep my ends from drying and breaking, but it's far too expensive for me to consider it a must-have.

Just so-so
-10.21.12
Quick Take: lightweight
I thought this would make my damaged ends more manageable, while stimulating my hairgrowth with topical vitamins. I'm not sure it did either. It was super lightweight and didn't change the texture of my hair much (which is a bit wavy and dry, with lots of flyaways). I felt like I had more breakage than usual, and my ends tangled more easily, though dry weather and changing of other hair products effected that as well. I was disappointed because I thought this product would save me: This summer I've been experimenting with many products in order to help my hair recover from abuse with dye and a flat iron. I've been furiously avoiding non-healing and silicone products. This product sounded like it fit the bill, but has not helped much. My scalp feels a bit healthier, but overall, this product didn't accomplish much for me... The battle rages on to look presentable at work with non straw-ended hair and minimal effort.

Adds volume
-10.10.12
Hi
Hard to tell if it made my thinning hair grow faster, but it DID add volume-lots of it. ..and it is not greasy.
It is expensive though--and a little does NOT go a long way. I am on my 2nd bottle. I have been using it every night;

Quick Take: easy to use, quick results, hair softening, makes hair shiny
I have been a fan of Ouidad products for years. i'm so excited to see these new salon series treatments from them. I have only used it a few times so i can't review hair growth properties yet, but this serum does not feel heavy or oily whatsoever on my hair. I used a dropper and put it on my hair, which is super dry, frizzy, damaged and curly and it make it so very shiny and super soft! I take biotin internally for it's benefits and think it is cool to see it in a topical form. Looking forward to seeing how this heals my hair long term =)
