## Description

Benefits: - Instant scalp coverage - Conceals hair loss and thinning areas - Creates dramatic density and volume - Last until your next shampoo Key Ingredients: - Keratin: Revitalises the hair's natural protective layer, adds strength, restores elasticity and reduces breakage. To use: Apply on dry hair only. Shake can well. Hold 3-6 inches (8-15cm) from hair and spray on balding and thinning area with a steady movement. Allow product to dry in hair 2-3 minutes.

Review: Doesn’t come close—huge fail - I really had my hopes up for this but unfortunately this was a massive let down. The shaken in hair fibres is still the best way to go by far. This melded well with the hair but did not for the balding areas where as toppik or surethick works wonders. The aerosol makes it wet and too much pressure. Huge miss, wayyyyy too expensive. Truly disappointed I was excited for a quicker easier spray solution to the fibers but I will go back to those. Really wish I could return this.
Review: Better than the other 20 products I’ve tried - Literally the best I’ve tried so far. I just do small spot sprays on top (crown) since that’s where I’m thinning the most. Then I do a dry-touch hairspray lightly over it and that’s it. Looks real, even in sunlight walking around Disney sweating in the summer. Nothing came off when sweating and you can’t clock it even up close. I’ll come back and post pics soon.

### ⭐ Doesn’t come close—huge fail
*by A***R on 19 September 2024*

I really had my hopes up for this but unfortunately this was a massive let down. The shaken in hair fibres is still the best way to go by far. This melded well with the hair but did not for the balding areas where as toppik or surethick works wonders. The aerosol makes it wet and too much pressure. Huge miss, wayyyyy too expensive.

### ⭐⭐⭐⭐⭐ Better than the other 20 products I’ve tried
*by J***M on 4 July 2026*

Literally the best I’ve tried so far. I just do small spot sprays on top (crown) since that’s where I’m thinning the most. Then I do a dry-touch hairspray lightly over it and that’s it. Looks real, even in sunlight walking around Disney sweating in the summer. Nothing came off when sweating and you can’t clock it even up close. I’ll come back and post pics soon.

### ⭐ Not subtle it’s dark can’t blend at all
*by L***N on 4 September 2025*

Really dark greasy and not subtle/buildable it’s zero to HELLO (painted head) if tons of scalp AND graying are present. I’m imagining long straight glossy long black hair with a too-wide part this might work
