After trying it out and learning more about it, I wanted to share my experience and some tips to help you decide if it’s the right product for you.
What Is Paul Mitchell Thicken Up?
Paul Mitchell Thicken Up is a lightweight volumizing spray designed to add body and fullness to fine or limp hair. It uses a blend of botanical ingredients to create texture and lift while maintaining a natural feel. I found that it works well both on damp hair before styling and on dry hair for touch-ups.
Who Is It Best For?
From my experience, this product is ideal for anyone with fine to medium hair who wants a boost in volume without the crunchiness or stiffness that some volumizers can cause.

- Lightweight feel: Unlike some heavy mousses or gels, it didn’t weigh my hair down or leave residue.
- Natural finish: My hair looked natural, not overly styled or sticky.

What to Consider Before Buying
- Hair type: If your hair is extremely fine or very oily, you might want to test a small amount first to see how it reacts.
- Scent: It has a mild, pleasant fragrance, but if you’re sensitive to scents, check it out in-store.
