Instantly Thick Biotin Conditioner, 8.45 oz - Volumizing & Moisturizing Hair Product for Thin, Flat or Dry Hair - Paraben-free, Sulfate-free, Phthalate-free

The shampoo is amazing for making your hair look thicker; just leave it on your hair for 1 minute before you wash it out, then blow dry it. Excellent stuff.

This smells really good and leaves my hair soft and easy to brush out. My boyfriend even commented on my hair looking better after I switched to this conditioner without knowing I changed anything.

Due to medical reasons my hair is falling out and thinning! I put this on wet hair and it gives it volume and hair feel thicker. I’m obsessed! If I blow dry it makes my hair feel thicker and if I air dry my hair stays wavy curly.

Is a good detangler. But doesn’t help hair growth.

Makes my hair so thick, when I was losing weight my hair was falling out, now my hair is thick and shiny, and this shampoo and conditioner are why. I wish I could take it with me to the hairdresser because she uses their own product and I love this volumizing conditioner better than their expensive products. Highly recommend!

Has a great scent that pairs well with the dove shampoo I use. Made my hair oddly dry and often frizzy once fully dry. Had to use a detangling spray after getting out of the shower because it just made it so knotted and dry. Lots of volume in my hair but not a big fan of the work I've been putting into to brush my hair, as well as having to add so many extra products.

This conditioner did amazing! My thin colored treated hair is usually very dry. But this conditioner softened my hair and made the curls come back to life after just one treatment! I will definitely be buying this product, Marc Anthony Thick Biotin Conditioner again!

I like this a lot. I have fine thin hair and this gave me volume without the product itself being too heavy or making my hair greasy.

J'avais acheté le shampoing volume et je lai beaucoup aimé alors j'ai acheté l'après shampoing volume. J'ai les cheveux fins et il est efficace. Un peu plus de volume c'est parfait pour moi. Bonne odeur.

I’m a bit surprised by the positive reviews. I have thin hair and have used conditioners that genuinely added volume, but this one doesn’t. It seems to change the texture slightly, but it doesn’t create any noticeable volume.

This is amazing, does what it's suppose to do. All of this name brand works freaking good.

Great product

I buy the Marc Anthony instantly thick hair products because they really do work well on fine hair. Using this brand of shampoo, conditioner and styling cream definitely gives fine hair more body and actually makes it look thicker. Fine hair has a tendency to fall flat even when using hairspray but with this stuff it doesn't and it also holds curls better too. I haven't noticed that it actually thickens hair but it does give the appearance of thicker hair, which I really appreciate.
