My Hair Is Thin and Flat, But No One Knows Because of This Shampoo

A lot of us have our own hair gripes, right? Personally, I like my hair for the most part—it's stick-straight and easy to manage, which is great because I'm 100% lazy when it comes to styling or using any other products aside from shampoo and conditioner. Most days, I just air-dry it and call it a day.

That doesn't mean I don't get frustrated with my strands, though. My biggest hair complaint is that because it's stick-straight, it's very flat and on the thinner side. It seriously cannot hold a curl at all. I can spend all this time with my curling iron, and then, guaranteed, an hour or two later, it slowly deflates and becomes straight again. The same goes for any type of volume—I've tried so many products to get that big, pumped-up hair, but many have failed me.

Since I've done a lot of trial and error, I have found a few products that are helpful in the volume department. So I haven't been completely hopeless. And although I know I'll never get my hair to sky-high levels, these products do give it a little more oomph. One of my holy-grail hair-thickening products is R+Co's Dallas shampoo and conditioner. This product really gets the job done for me.

It's infused with vitamin B5 and biotin, so it's super nourishing—both ingredients hydrate the strands and strengthen the keratin structure of hair, making your hair look and feel a lot fuller and healthier. Neither the shampoo nor the conditioner weigh my hair down, which is a huge plus. And whenever I use the two products, my hair feels a little bouncier, shinier, and stronger. What more can you ask for, really? It's my everyday shampoo-conditioner duo for sure.
