MONDAY HAIRCARE Volume Shampoo for Thin, Fine Hair — 798 mL with Hydrolyzed Collagen & Macadamia Oil

MONDAY Haircare VOLUME Shampoo is a paraben- and sulfate-free cleansing formula with hydrolyzed collagen and macadamia oil designed to add body and shine to thin, fine, or flat hair.

This roomy 798 mL bottle delivers a salon-style volume boost without heavy residues. The formula pairs a lightweight collagen-derived protein to help plump strands with macadamia oil to smooth and reflect light, while remaining pH balanced and dermatologically tested. MONDAY Haircare is cruelty-free under the Leaping Bunny programme and PETA certified, packaged in a recyclable bottle for lower environmental impact.

How does this shampoo create noticeable fullness?

The shampoo uses hydrolyzed collagen — a protein broken into smaller fragments — that temporarily fills and coats individual fibers, making each strand feel thicker and appear more substantial. Gentle surfactants cleanse scalp oil and build-up so hair lifts at the roots rather than becoming weighed down.

• Hydrolyzed collagen helps plump the hair shaft for enhanced body
• Lightweight cleansing removes excess oil that flattens roots
• Sulfate-free base reduces harsh stripping that can flatten texture
• Large 798 mL size supports daily or frequent use

Will this formula preserve shine while adding volume?

Yes — macadamia oil is included primarily as an emollient to smooth the hair cuticle and enhance light reflection, so hair looks glossy rather than dull or frizzy. The balance of conditioning and protein treatment aims to lift strands while keeping them soft to the touch.

• Macadamia oil adds light-reflecting sheen without heaviness
• pH balanced formulation helps maintain hair surface integrity
• Conditioning agents prevent the dry, brittle feel sometimes caused by volumizing products

Is this gentle enough for frequent use and sensitive scalps?

The shampoo is dermatologically tested and formulated without parabens and sulfates, making it suitable for many users who wash regularly. Because it avoids strong sulfates and includes balancing ingredients, it tends to be less irritating than harsher clarifying shampoos, though individual sensitivities vary.

• Dermatologically tested for general scalp compatibility
• No parabens or sulfates to reduce potential irritation
• pH balanced to support scalp and strand health

How should I integrate this shampoo into my routine for best results?

Use it as your primary cleansing step — massage into wet hair focusing on roots, rinse thoroughly, and follow with a lightweight conditioner or MONDAY Haircare Volume conditioner for added lift. For finer hair, consider alternating this shampoo with a gentler daily cleanser if you use heavy styling products often.

• Apply to wet hair, lather at the scalp, rinse well
• Pair with a volumizing conditioner for balanced manageability
• Use regularly to maintain body but rotate if heavy styling product buildup occurs

Who is this for: MONDAY Haircare VOLUME Shampoo is formulated for people with thin, fine, or flat hair seeking fuller-looking strands without heavy silicones or harsh sulfates. It suits those who want a cruelty-free, dermatologist-tested option in a large, economical bottle — ideal for daily users, families, or anyone who prefers less frequent restocking. If you need maximum lift with lightweight conditioning and prefer products vetted for ethical testing, this shampoo is a practical choice.
