Works Great!
I'm 49 and my hair has been through a lot. It's thinning, frizzy, and just doesn't look like it used to. I've tried so many deep conditioners and masks over the years—some were too heavy, some didn't do anything, and most just left me disappointed. I wasn't expecting much when I grabbed the Wella Ul...

Hair Type Wavy Hair
This is so effective for my frizzy hair . The scent is perfect, not overpowering but just right. After using it, my hair feels incredibly soft, and i noticed way less breakage when brushing. It's definitely worth the price compared to drugstore brands I've tried before.

Nice conditioner
Hair Type Very Curly Hair
This is a good brand in general, and I'm not disappointed with the conditioner. It leaves my hair soft and tangled free for a couple days. The scent is odd to me though. It's very masculine and musky. I prefer citrus, but it's not a deal breaker. I'd buy it again. For reference, I have long, curly hair that is color treated.

Great serum!
