Why You’ll love it

Feel your hair grip and hold like it used to.

Helps hair look denser from root to tip.

Light, non-greasy finish that won’t weigh strands down.

Makes styling fine hair easier, with better control and texture.

Description

KEVIN.MURPHY THICK.AGAIN is a leave-in thickening treatment that helps hair look fuller and stronger.

This lightweight formula is designed for men’s fine or thinning hair, especially on the crown and hairline. It works by coating each strand to create a denser, more solid feel while helping to reduce breakage over time.

The fluid texture spreads easily through towel-dried hair without stickiness, drying down to a natural, flexible finish. Hair feels grippier, easier to style, and less wispy, with a clean, subtle scent that doesn’t overpower.

Use it as part of your daily routine before blow-drying or styling. Ideal for anyone wanting their hair to look thicker, firmer, and more controlled, without heavy waxes or crunchy sprays.

Directions

How To Use KEVIN.MURPHY THICK.AGAIN

Spray or dispense evenly through areas of thinning or weakness.
Gently massage into scalp with fingertips.
Do not rinse out.
Style as usual, preferably with a hairdryer for extra thickening.
Use daily or as recommended by your stylist.
