Hair Biology Volumizing Shampoo + Conditioner & Thickening Treatment Set — Biotin, Color-Safe (12.8/12.8/6.4 fl oz)

Hair Biology Full & Vibrant Set is a three-piece haircare system — volumizing shampoo (12.8 fl oz), conditioner (12.8 fl oz), and a 6.4 fl oz thickening treatment — formulated to add lift, lightweight moisture, and strand thickness for thin or fine hair.

This trio was developed to address common signs of thinning and flattening that come with aging or fine hair types. Each product combines cleansing, lightweight conditioning, and an instant thickening formula enriched with biotin and free from parabens and dyes. The set is intended for color-safe use and designed to deliver fuller-looking hair without weighing strands down.

How does the shampoo add volume without drying hair out?

The Volumizing Shampoo gently removes oils and buildup while preserving hydration so hair feels clean but not stripped. Its lightweight surfactants are selected to lift roots and leave hair primed for conditioning and styling.

• Weightless cleansing that reduces residue on the scalp
• Formulated for fine or thinning hair to avoid heaviness
• Safe for color-treated hair so pigments stay vibrant

What does the conditioner do for fine or flat hair?

The Volumizing Conditioner provides targeted moisture and slip to smooth strands without adding bulk. It helps restore softness and manageability while supporting a fuller visual profile when used with the shampoo and treatment.

• Lightweight conditioning to detangle and soften
• Designed to maintain root lift and overall body
• Paraben- and dye-free formula compatible with colored hair

How does the Thickening Treatment create fuller-looking hair?

The Thickening Treatment is a spray-on formula that quickly coats each strand to produce immediate perceptible thickness and reduce the appearance of breakage. It contains ingredients formulated to adhere to hair fibers, giving the hair more presence from root to tip without stiffness.

• Spray application targets roots and scalp areas needing density
• Installs a temporary thickening layer on individual strands
• Instructions: spray 15 pumps across root zone and massage for best coverage

Is this set suitable for color-treated or mature hair?

Yes — the Full & Vibrant Set is formulated to be gentle on color-treated and aging hair types. Ingredients were chosen to protect color vibrancy and support hair that may experience texture changes over time, while avoiding parabens and dyes.

• Safe for use on colored and grey-treated hair
• Biotin-infused formulas to help hair look stronger and more luminous
• Free of parabens and added dyes for gentler daily use

Who is this for: The Hair Biology Full & Vibrant Set is aimed at people with fine, thin, or flat hair — including those noticing age-related changes — who want a straightforward routine that cleanses, conditions, and immediately boosts strand thickness. It’s a practical choice for anyone seeking lightweight volume, color-safe formulas, and an easy-to-follow application for fuller-looking hair.
