MONDAY HAIRCARE Volume Shampoo for Thin, Fine & Flat Hair — 354 mL with Hydrolyzed Collagen & Macadamia Oil for Lightweight Lift a

Designed for hair that needs lift rather than weight, this VOLUME Shampoo blends hydrolyzed collagen with macadamia oil and gentle surfactants to create fuller-feeling strands while maintaining a balanced scalp pH. The formula is dermatologically tested, cruelty-free certified (Leaping Bunny and PETA), and presented in a recyclable bottle, so it’s aimed at people who want visible fullness with cleaner ingredients and responsible packaging.

How does this shampoo make thin hair look fuller?

Hydrolyzed collagen in the formula adheres to the hair shaft, temporarily increasing strand diameter and improving the hair’s perceived volume. Combined with mild cleansing agents, the shampoo cleans without stripping, allowing styled lift that lasts through the day.

• Hydrolyzed collagen helps plump individual strands for increased body.
• Gentle surfactants remove buildup without weighing hair down.
• pH-balanced base supports healthy cuticles and manageability.

Will the macadamia oil make my hair greasy?

Macadamia oil is included in a lightweight concentration to restore shine and softness without heavy residue. When used as directed—apply to scalp and lengths, lather, then rinse—most users report improved sheen and smoother texture without excess oiliness.

• Light emollient action enhances shine while remaining non-greasy.
• Balanced formulation prevents product buildup when rinsed properly.
• Suitable for fine hair when used as part of a volume-focused routine.

Is this shampoo safe for sensitive scalps and color-treated hair?

The shampoo is dermatologically tested and free from parabens and sulfates, which reduces common irritants for sensitive scalps. While the formula is milder than many clarifying shampoos, always patch-test if you have a known sensitivity and consult your colorist about frequency for color-treated hair.

• Dermatologically tested to minimize irritation risk.
• Paraben- and sulfate-free to be gentler on scalp and color.
• pH balanced to help maintain cuticle integrity and prolong color.

How should I use this shampoo for best results?

For fuller-looking hair, apply a small amount to wet hair, focusing on roots, then work a gentle lather through the lengths before rinsing. Follow with a lightweight conditioner or leave-in product concentrated on ends to avoid weighing roots down.

• Use on wet hair, concentrate at the roots for lift.
• Rinse thoroughly to prevent residue that can flatten hair.
• Pair with lightweight conditioners and styling products for lasting volume.
