How to Choose Your Hair Thickening Products

For the best hair thickening products for instant volume, the Color Wow Bombshell Volumizer is the hero choice — its lightweight formula delivers extraordinary root lift and body without stiffness or residue. Apply to damp roots before blow-drying and lift the hair at the root as you dry for maximum volume. The Color Wow Raise the Root Thicken & Lift Spray is a brilliant companion product, applied directly to the root for targeted thickening and lift.

For shampoo for thinning hair and a complete hair growth routine, the Lustrao Hair Growth Shampoo and Conditioner are specifically formulated to support hair thickness and density with regular use. The Grow Gorgeous Hair Growth Serum is a targeted scalp treatment applied between washes to support hair growth from the follicle. The Color Wow Youth Juice Collagen Scalp Treatment delivers collagen directly to the scalp to support hair density and fullness over time. For fine hair products that add texture without weight, the Seven Potions Salt Texturizing Spray and Living Proof Perfect Hair Day Advanced Clean Dry Shampoo both add grip, texture and volume without heaviness.

Application Tips for Fine & Thinning Hair

For maximum volume with hair thickening products, always apply volumising sprays and root lifters to damp — not wet — hair for best results. Blow-dry with a round brush, lifting the hair at the root and directing the airflow downwards along the shaft for smoothness and volume simultaneously. Avoid applying conditioner to the roots if you have fine or thinning hair — apply only from mid-lengths to ends to prevent weighing down the root area. The Philip Kingsley Body Building Conditioner is specifically formulated to be lightweight enough for root application. Use dry shampoo — such as the Living Proof Perfect Hair Day Dry Shampoo — at the roots between washes to absorb excess oil and add texture and volume.
