An absolute no.

Excited to try this sample I received. The smell was absolutely horrific. I didn’t like the way it left my hair feeling. Felt almost more tangled and greasy.

Horrible smell

I received a sample packet of this product with another order and this was absolutely awful. I don't care what it does to my hair - it could be a complete miracle for damage repair for all I care. It smells SO BAD. It's like very old tea that's been left out too long. It stunk up my shower for way too long and I couldn't wait the 4 minutes to rinse this out of my hair.

I use this on days when i don't use a conditioner in place of it so about twice a week. It makes such a huge difference in repairing my color and heat damaged hair. My hair is extremely brittle and dry no matter what i do and this add a beautiful shine and silkiness to them

I actually love what this does to my hair. It works really good at making my hair soft, smooth and handling my frizz. It smells so good and the smell definitely lasts long. I will be using this all summer long,I can see it helping so much especially after the pool because I don’t want my hair chlorine damaged.

new favorite product~

I am in love with the BondiBoost Bond Builder+ Leave-In Hair Mask. It makes my hair feel so soft and smooth without feeling heavy or greasy. My ends look healthier and it definitely helps with frizz. I also like that a little goes a long way. I highly recommend :)

A Game-Changer for Fine, Straight Hair!

I normally use another brand's leave in conditioners. Then I had an opportunity to try the Rapid Repair Bond Builder+ Leave-In Mask and I think I'm changing products! I noticed a difference right away. I often don't have time to blow dry my hair and needed a leave in conditioner that I can use if I air dry or blow dry. My hair is fine and straight. It acts like it wants to curl but it doesn't. This product makes my hair shiny, soft and I have volume! And, after putting my hair up in a bun, when I take it down I actually have waves and/or curls (depending on how long my hair was up). This is definitely going to replace my other leave in conditioners.

I love it and I will buy it again

Delighted with this product, look, I'm an old lady and the truth is that I was surprised because my hair is brittle and the truth is that I was surprised
