Can be drying

I have thin hair that is lacking density, though it is wavy/curly. If you use this with the conditioner it can cause some moisture loss or brittleness so I suggest it with either ultra moisturizing styling products or a good moisturizing conditioner instead. I do notice a difference in my hair growth and density though!

Thanks for sharing your experience with DALLAS! We're glad you're seeing positive results with hair growth and density. For those with wavy/curly hair types looking for extra moisture, we recommend pairing DALLAS with our De Luxe Reparative Masque for deep hydration. You can use this as your conditioner 1-2 times per week to combat any dryness while still getting the volumizing benefits of DALLAS shampoo.

Great Cleanser

I recently tried the Dallas Thickening Shampoo, and I have to say, it cleanses my hair really well. My scalp feels refreshed, and my hair is left feeling clean without being stripped of moisture. The best part is the fragrance—it has a very pleasant, light scent that lingers without being overwhelming.

That said, even after following up with the Dallas Thickening Conditioner, I noticed my hair still feels a bit tangled. Despite using both products, it seems like I still need a detangling product to help smooth out my hair.

So while the shampoo and conditioner combo does a great job at cleaning and smells fantastic, you may need an extra detangling step to keep your hair smooth and manageable.

Worthy Investment!

The liter size is far superior to the 8oz. I love the pump and wish the 8oz had a pump.
