Makes a difference but doesn't smell good

I think it does make my hair appear thicker, but I'm really not a fan of the way it smells.

Thank you so much for your honest 4-star review, Min-Yee! ✨ We're thrilled to hear that our DALLAS Biotin Thickening Treatment is delivering the thicker-looking hair results you're noticing - that's exactly what our biotin-powered formula is designed to achieve!

We're really sorry to hear that the scent isn't working for you though. We totally understand how important fragrance is to the overall product experience, and when a smell doesn't click with you, it can really impact how you feel about using it even when the performance is great.

We completely get how this can be frustrating - especially when you're seeing those amazing thickening results but the scent is holding you back from fully loving the experience. Your feedback about this is incredibly valuable to us, and we really appreciate you sharing both the positives and the areas where DALLAS isn't quite hitting the mark for you.

It means so much that you're still giving DALLAS 4 stars despite the scent concerns, and that you're noticing those thicker hair results. Your honest input helps us understand what matters most to our customers when it comes to both performance and the sensory experience! 💫

With gratitude,
The R+Co Team

Bodacious hair!

It feels light when you put it on and doesn’t detangle quite like a conditioner, but it still delivers big results! My fine hair felt much fuller with lots of great volume! Doesn’t weigh my hair down.

Very Pleased

I have been using the Dallas shampoo, conditioner and treatment masque for about a year. My hair is finally looking so much better in thickness and overall health. In fact, I have been getting compliments from due to the noticeable difference,. Now 3 of my girlfriends have ordered the line as well. Will certainly continue to use and highly recommend.
