Fine, thick hair likse it, good not amazing - SUN BURN RISK!
I've been experiencing severely dry hair from low iron; dry, brittle and like straw. I have never used a leave-in before and did careful research on finding a lightweight leave-in for my hair situation and that wouldn't leave residue the next day. I landed on this product. I wouldn't say this is my ...

Matrix and Bzz Agent gifted me Matrix's Instacure Build-A-Bond Super Sealing Leave-in Balm to try in exchange for my honest review, but all thoughts on the product are my own.

This Insta Cure Build A Bond leave in is the best thing since sliced bread for me! Matrix has some really good innovative products lately and this is definitely up there as innovative. I just apply a small amount to my damp hair from mid length to my ends and work through my hair using my brush. My hair is always so difficult to brush out after a shower because it's very dry. With this product my brush glides through my hair with ease. After I dry it my hair is so soft, shiny and healthy looking. It's my new favorite hair product and I hope it stays around forever! I definitely recommend Matrix Insta Cure Build A Bond leave in.

This is a leave in product. I use just a small amount of this product on the ends up to about the middle part of my hair leaving the scalp free of product. So far my split ends appear to be getting better. It will be a process since I get my hair highlighted a few times a year and I have fine, thin hair. I use this in conjunction with the Matrix Instacure Revival Liquid Mask. I am hoping with time, my hair will be transformed as it is doing a pretty good job so far with only a few wees of using it.


I would definitely buy it again

Did not work for me

I received the Instacure Build-A-Bond Instant Revival Liquid Mask and Instacure Build-A-Bond Super Sealing Leave-In Balm in exchange for my honest review. I tried the products for a week and a half when I decided it was not for me. For background reference I have bleached hair, so I have damage obviously. When I received the email I was getting the product I thought oh great something that might make my hair a bit healthier. These products did not help me at all. I do have frizzy, thick, coarse hair so that may be a reason as to why it didn't work well on me. For me it felt like my hair felt worse than when I wasn't using it. I feel like it caused me more damage and slpit ends. Once I went back to my regular regime my hair went back to feeling a bit normal. If you're on the fence on buying I wouldn't say not to try it because every hair is different. What might work for me might now work for you, but on my hair type it did not work.
Nice Leave In for Curly Hair

I am a fan of matrix products in general. I have used the Brass Off line most recently so I was excited to try the Build-A-Bond line. I have long curly hair that is sometimes really hard to brush when I get out of the shower. I haven't had the chance to use this product for very long but I can say that this product seems to have made brushing a lot easier. As a curly girl I am always on the hunt for a great leave in. This is my first time using a leave in balm. I do think it made my hair more manageable. The scent is pleasant and the packaging is cute. I was interested to see how this product compared to Olaplex and I still think Olaplex wins for curly hair but this is a great option! Thank you BzzAgent for the opportunity to review this product in exchange for my honest review.

Is this good for bleached and colored pink hair?
- Asked by Pink Rose
- Official Answer By Matrix - Brand EngageHello! Yes, Matrix Instacure Build-A-Bond Super Sealing Leave-In Balm can be used on bleached, color-treated hair, including pink hair. It helps smooth and protect damaged-looking lengths, but it won’t preserve or refresh pink color on its own.Was this answer helpful to you
