Reviews Summary
Customers say this hair treatment adds noticeable volume to fine and thin hair. Many reviews highlight its lightweight feel and ability to create fullness without leaving residue. While most users see immediate volumizing effects, some note results vary when used on wet versus dry hair. Reviews mention the product works well for styling without weighing hair down. Some users experience texture changes, with a few noting their hair feels dry or stiff. Most appreciate that it integrates easily with other styling products, though results can vary based on application method and hair type.

    It works

    Works on my fine hair, not heavy or greasy.

    Use it after every wash for styling with hot brush.

    I really like this product!

    After shampoo and conditioning but while my very fine hair is still wet I use this and then blow dry and it really adds volume.
