A leave-in thickening treatment for fine or thinning hair — eyelash plumping technology and a powerhouse of scalp and strand ingredients build visible thickness instantly and with continued use, with heat protection up to 216˚C / 420˚F.
The Moda Team Review
Thick Again was developed from the same eyelash plumping technology that underpins Body Mass — the scientifically proven system that physically builds thickness at the strand level using Biotin-fortified ingredients and scalp-stimulating botanicals. Kevin Murphy created it specifically for fine or thinning hair that needs more than a volumising shampoo and conditioner can deliver on their own.
The difference between this and a standard thickening spray is what is happening beneath the surface. Nettle Extract fortifies the hair fibre and assists in preventing breakage. Horse Chestnut improves microcirculation to the scalp. Baobab repairs and moisturises. Used consistently for 14 days as part of the Stimulate Me trio — Wash, Rinse, Thick Again — Kevin Murphy describes the hair as transformed. These are not styling claims; they are treatment claims.
Why Moda Carries This
As a White Haven Kevin Murphy salon, Thick Again is the leave-in we reach for when a client's concern is density rather than just volume. Volume is about lift and movement at the root. Density is about how much hair is actually there and how strong each strand is. This product addresses the second problem, and it does it with a heat protectant built in — so it works with any styling routine without adding another step.
Key Active Ingredients
-
Eyelash Plumping Technology (same as Body Mass): Scientifically proven technology that physically builds strand thickness and delivers body.
-
Nettle Extract (Urtica Dioica): Fortifies hair fibres, helps thicken the hair, and assists in preventing breakage.
-
Nelumbo Nucifera (Lotus) Flower Extract: Boosts natural shine on damaged hair while adding volume, body and elasticity to dry and brittle strands.
-
Aesculus Hippocastanum (Horse Chestnut) Seed Extract: Helps improve microcirculation to the scalp — supporting a healthier environment for hair at the root level.
-
Hydrolyzed Wheat Protein: Improves body, boosts shine, and leaves hair feeling deeply nourished and conditioned.
-
Adansonia Digitata (Baobab) Fruit Extract: Repairs damaged hair, increases strength, and moisturises dry hair for greater manageability.
Moda Pro Tip
Concentrate the spray at the roots and scalp rather than distributing evenly through the lengths. Fine and thinning hair loses density at the root first — that is where the Horse Chestnut microcirculation work and the plumping technology need to land. The lengths benefit from the Baobab and Wheat Protein, but the root is the priority.
Not the Right Fit If...
If your concern is volume and movement rather than strand density and scalp health, Body Mass or Full Again target the blow-dry styling outcome more directly. Thick Again is a treatment-first product — it builds thickness over time with consistent use. If you want immediate volume from a styling product alone, it works, but it is not its primary strength.
How To Use
- Prep with Stimulate Me Wash and Rinse, then towel dry.
- Spray Thick Again evenly throughout damp or towel-dried hair.
- Concentrate at the roots and scalp.
- Do not rinse — leave in.
- Dry and style as usual. Safe for heat styling up to 216˚C / 420˚F.
- Use consistently for 14 days for full treatment benefit.
