Kevin Murphy Thick Again

Fuller-Looking Hair From the Very First Use

Kevin Murphy Thick Again is a leave-in thickening treatment designed for fine or thinning hair that wants to look and feel denser. It coats and thickens the individual hair shaft so each strand takes up more space, which translates to noticeably fuller-looking hair with more volume, texture, and presence. If you look at your hair and feel like there should just be more of it, Kevin Murphy Thick Again is one of the most effective products we carry for that exact feeling.

Best For

• Fine or thinning hair that looks sparse or flat
• Anyone who wants their hair to feel denser and more substantial
• Hair that is naturally fine and has always lacked body
• Anyone experiencing gradual thinning and wanting more fullness

What It Helps With

Lack of density, flatness, and the visual thinness that makes hair look sparse even when it is healthy. Kevin Murphy Thick Again works by coating the hair shaft with thickening polymers that make each strand feel and appear fuller. The effect is cumulative too, so with regular use your hair starts to look and feel consistently denser and more voluminous.

How to Use

Apply to clean, damp hair before blow drying. Work through from roots to ends. No rinsing required. Style as usual. For the most impact, focus application on the roots and scalp area where density loss is most visible.

Pro Tip From Our Stylists

Kevin Murphy Thick Again is especially powerful when combined with a blow dryer and a round brush at the roots. The heat helps set the thickening effect so your hair holds its fuller shape longer. Clients who use this as part of a consistent routine tell us it is genuinely one of the most noticeable improvements they have made to their hair, particularly if they have been dealing with thinning for a while.
