Nice treatment but the smell

The treatment is really nice for my fine hair, but the only issue is I can't use it as often as I should because I can't stand my hair smelling like this after. I would describe the scent as Axe body spray adjacent.

Thank you for your honest 3-star review about our DALLAS Biotin Thickening Treatment, Hayley! ✨ We're so glad to hear that the treatment is working really well for your fine hair - it's wonderful that you're experiencing the thickening benefits the formula is designed to deliver!

We're really sorry to hear about your experience with the scent though. We totally understand how fragrance can be such a personal thing, and when a scent doesn't work for you, it can really impact how often you feel comfortable using a product. Your "Axe body spray adjacent" description definitely gives us a clear picture of what you're experiencing, and we can see how that would be off-putting for your hair routine.

It's especially frustrating when you love how a product performs but the scent holds you back from using it as frequently as you'd like to get the full benefits. We know consistency is key with treatments like DALLAS, so we completely understand your dilemma about not being able to use it as often as you should.

Your feedback about the scent is incredibly valuable to us. We appreciate you taking the time to share both what's working well (the treatment benefits for your fine hair) and what's challenging (the fragrance experience). This kind of detailed input really helps us understand the full customer experience with our products! 💫

With gratitude,
The R+Co Team

Good addition to Dallas line

Although this isn’t super moisturizing, it definitely adds strength and is a nice swap for the conditioner once a week. If you like the Dallas line, highly recommended

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.
