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

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

This salon-inspired shampoo blends targeted actives and gentle surfactants so hair feels fuller without heaviness. The formula uses hydrolyzed collagen to support strand structure and macadamia oil to smooth and enhance sheen, while remaining pH-balanced and dermatologically tested. It’s also cruelty-free (Leaping Bunny and PETA certified) and packaged in a recyclable bottle for mindful daily use.

How does this shampoo build volume without weighing hair down?

The shampoo uses light, film-forming hydrolyzed collagen to give strands a fuller feel and improve temporary body. Instead of heavy oils, macadamia oil is included at a measured level to impart shine without residue. The cleansing system removes buildup so root lift is easier to achieve with styling.

• Hydrolyzed collagen adds temporary strand thickness and structure
• Macadamia oil provides non-greasy shine and smoothness
• Balanced surfactants cleanse buildup that flattens roots
• Lightweight formula avoids weighing fine hair down

Is the formula safe for sensitive scalps and color-treated hair?

The blend is dermatologically tested and pH balanced to be gentle on the scalp and hair cuticle. It’s free from parabens and sulfates—ingredients commonly avoided by those with sensitivities or color-treated hair. Always patch-test if you have a history of reactions.

• Dermatologically tested for skin compatibility
• pH-balanced to protect color and cuticle integrity
• No parabens or sulfates to reduce harsh stripping
• Suitable for routine use on delicate scalps

How should I use this shampoo for best results?

Apply to wet hair, massage into scalp and roots until you form a light lather, then rinse thoroughly. Repeat if hair is particularly oily or product-laden, then follow with a light conditioner focused on mid-lengths to ends. For added lift, dry hair upside-down while styling.

• Wet hair thoroughly before application
• Massage into roots and scalp for lift-focused cleansing
• Rinse well; repeat if needed for heavy buildup
• Pair with a lightweight conditioner and volumizing styling products

What ethical and packaging claims does MONDAY Haircare make?

MONDAY Haircare emphasizes cruelty-free certification and recyclable packaging to align with eco-conscious shoppers. The brand holds Leaping Bunny approval and PETA certification, and the large 798 mL recyclable bottle reduces waste compared with smaller, single-use sizes.

• Certified cruelty-free: Leaping Bunny and PETA
• Recyclable bottle to minimize plastic waste
• Large 798 mL size reduces frequency of repurchase
• Formulated without parabens or sulfates

Who is this for? MONDAY Haircare VOLUME Shampoo is made for people with thin, fine or flat hair who want an easy, everyday product to boost body and shine without heavy residues. It suits those who prioritize gentle, dermatologically tested formulas and cruelty-free credentials, and anyone looking to replace harsher surfactants while still achieving noticeable lift and smoothness.
