Advanced ClinicalsHair Spray Thicken & Shine Leave In Treatment, Nourishing Detangling Formula for Fine, Damaged, or Frizz Prone Hair, Supports Scalp Health for Strong Thick Hair, 8 Fl Oz

My hair is very fine and this leave in spray leaves my hair feeling and looking shiny and healthy and not so thin. I spray it right on towel dried hair and let it dry naturally and it just feels like I have a much fuller head of hair. And, it smells good too!

As a 65 yr old with long thinning hair, I just love this. It brings back the shine I once had naturally and just gives it a very healthy look. I turned my daughter on to it and she loves it. So does her husband!!! Try it!! You won't regret it if for nothing else, the unbelievable aroma. Smells very expensive.

I like that it adds a little texture to my hair

My hair thinning as I age; my sister turned me on to his product. Can't ssay enough wonderful things about it. Shampoo'd my hair, let it air dry..spritzed it and worked product thru my hair and proceeded to dry with round brush and hair dryer..I am so pleased!

Had to find a replacement product as the biotin product I like and have used for the past year is no longer sold at Amazon. I tried it out this morning and was happy with the texture and thickness the product provided. However, I am sensitive to smell and this product has a lasting odor that I could smell all day -- so unfortunately I will have to throw it away and try to find something else.

I really love this product! I spray the Advanced Clinicals Hair spray Thicken & Shine leave in treatment for my hair and it leaves it soft and manageable.

I used to love this product but they changed the formula and now it leaves a soapy residue and it's very thick in your hair. This product weighs your hair down and makes styling difficult. Would not recommend buying this anymore. So disappointed.

This spray adds shine, volume and softness. I have fine hair that is very curly. At one time, my stylists would say, "yes your hair is fine, but you have a lot of it." But as I have aged, my hair has thinned, additionally, I started going gray in my late thirties. Recently, I have decided to stop coloring and embrace the silver gray my hair has become. Though I do miss my brunette hair, the upkeep was getting to be too much because my hair grows pretty fast. My stylist removed the previous coloring and highlighted so I no longer had to deal with the granny halo. It did some damage, with dryness and frizz. I do use other bonding products, but this spray as the final part of my routine, well, lets just say I do not want to be without it. I have curly (thinning) hair; after shampooing and conditioning, I spray this in comb it through lightly and scrunch. I let my hair air dry and run my fingers through once when done and it looks great; full and shiny, with soft, frizz free curls. Love it.
