Not Good for Thin Hair
Sampled

I was very excited to try this sample. My hair is very thin, and when I used this product it left my hair feeling and looking greasy. My hair felt very soft, but it did look slightly oily. I think this product might work great on people with thicker hair, but for thin hair this product is a little too heavy.

Smells weird!
Sampled

This product smells weird and it leaves your hair in clumps! Pretty disappointing for a Toni & Guy product. I do not recommend.

I love Tony&Guy. Bbox introduced me to the line and now I've added the heat protector and this to my daily routine. Great stuff! Works well and smells good too!

Great product - not a great value.
Purchased

LOVE LOVE LOVE the product. It's the best serum I've found and I've tried them all.

Got the sample and purchased. Was EXTREMELY disappointed when it came in. My purchased bottle was the same size as the sample bottle. It's tiny.

Great product, but not a great value.

this makes my hair look smooth and put together t making it greasy. It gave my hair a professional feel at home and I am by no means a hair pro.

Love this serum

This hair product smooths without making my hair feel greasy or oily. I use it every day after I shower, applying it to damp hair. It helps tame the frizz and give my hair a great shine! I recommend other curly haired girls to try it out!

This serum is my new favorite hair product. I have very fine hair and this product does not give my hair a greasy feel. It smells amazing and the packaging is beautiful.

Smallest bottle ever
SampledPurchased

Works great. Controls frizz and adds shine. But completely overpriced for such a small bottle. I would like to find something comparable to this that's cheaper

Great serum

Loved using this on my daughters long hair! Mine is very short and a serum isn't need for me. However, her hair could just use a little of this serum and be ready to go!
