Hair Biology Volumizing Shampoo, Conditioner & Thickening Treatment Set — Biotin Infused, Color-Safe Volume for Fine Hair

Hair Biology Full & Vibrant Set is a three-piece biotin-infused haircare system — shampoo, conditioner, and a thickening treatment — crafted to add weightless volume and visibly fuller-looking strands for thin or fine hair.

As hair changes with age, lightweight formulas that cleanse, nourish, and temporarily thicken each strand can help restore shape and body without weighing hair down. This set pairs a volumizing shampoo and conditioner with a spray-on thickening treatment to lift roots, smooth strands, and enhance the appearance of density while remaining paraben- and dye-free and safe for color-treated hair.

How does this set add volume without making hair heavy?

The shampoo removes oil and buildup using a gentle, weightless cleansing base so hair feels clean but not stripped. The conditioner delivers light moisture that detangles and strengthens without coating the hair with heavy silicones or oils, preserving lift at the roots.

• Volumizing Shampoo: weightless cleansing and hydration for fine or flat hair
• Volumizing Conditioner: lightweight nourishment that restores softness and bounce
• Formulated to avoid heaviness that flattens root lift and body

What does the Thickening Treatment do and how do I use it?

The Thickening Treatment deposits a temporary thickening formula onto individual strands to create the look of fuller hair and reduce the appearance of breakage. It’s simple to use and can be applied to wet or dry hair to target roots and thinning areas.

• Spray 15 pumps across the root area, covering from earline upward for even coverage
• Gently massage into the scalp and style as usual; works under heat and between washes
• Contains caffeine to help the thickening ingredient adhere to hair fibers for instant visual density

Is this safe for color-treated or mature hair?

Yes — the Full & Vibrant formulas are free of parabens and optical dyes, designed to protect color vibrancy while offering age-conscious care. Ingredients are selected to be gentle on treated hair, helping preserve tone and shine as you add body.

• Color-safe formulation suitable for gray, highlighted, or dyed hair
• Paraben- and dye-free to reduce unnecessary irritation or fading
• Biotin-infused blends support the look of strength and luster in aging hair

Who is this for? The Hair Biology Full & Vibrant Set is aimed at people with fine, thin, or flat hair who want an easy, non-invasive way to amplify volume and improve the look of density. It’s well suited to anyone seeking lightweight daily care that works with color-treated or maturing hair — from those wanting subtle lift at the roots to users who need an instant fuller appearance for styling or special occasions.
