I really like this product now that I use it sparingly. When I first tried it, I found that it made my hair look greasy, but applying it just to the ends and not at the roots, leaves a nice, smooth, moisturized look. I like that it's easy to use and smooths out the frizzies and you don't need much product.

I do find it weighs down my hair, finally have to use so little and just at the ends which really does not much overall. At least not what the product claims. Nice concept, fragrant, but don't have the dry hair that perhaps is needed for this serum. Love TRESemme overall.

I did like the scent of this product, it was nice and clean smelling without that overwhelming perfume scent. I found the product was pretty good, especially for the price. I would try it again possibly, it was certain priced right.

My hair is just too oily for a product like this. Even when I just put it in my ends it weights my hair down and makes it appear greasy. I do like the texture and smell but this product is just not for me.

This works great for my dry ends from constant blow drying and straightening. It adds a nice shine to my hair and doesn't make the ends look so dry and brittle looking.

Keratin being the protein in hair; I only need a little Infusing Serum at my ends and it works well keeping my hair from frizzing and I believe strengthening it.

I enjoyed the feel of my hair after using this, however after a day my hair needed to be washed again. Would use once in a while but not every time I do my hair.

Not only do I dislike the scent,but it left my hair feeling more dry and damaged than before. I don't like this at all. I would not purchase this again.

I was happy with this. I used a little bit the first time because I was worried that it would be really oily and heavy. I didn't notice that. The next time I used a bit more and my hair was soooooo soft

I surprisingly really liked this. I thought it would weigh down my hair or make it oily and it did neither. It smells greats and makes your hair look less frizzy. Great product.
