This shampoo is intended for people with fine or thin hair who want more volume and body from their everyday wash. It's suitable for any hair length and works on all hair types, but it's specifically positioned — by Paul Mitchell itself — as ideal for fine hair rather than thick or coarse hair, which wouldn't need the same volumizing lift. It's a retail/consumer product (sold both in-salon and for home use), not a professional-only backbar item, and needs no special expertise to use.

The reason to reach for this over a plain volumizing shampoo is the combination of a stronger dual-surfactant cleansing base with panthenol layered in to offset the extra cleansing power — it lifts fine hair at the root while still leaving strands feeling conditioned rather than stripped. The tea tree, lemon, and sage combination also gives it a distinct scalp-tingling, citrus-herbal feel that's part of what the Tea Tree line built its reputation on.

Lather into damp hair and rinse. For best results, Paul Mitchell recommends following with the Tea Tree Lemon Sage Thickening Conditioner (and Thickening Spray, if using the full system).

Pros:

• Contains real tea tree leaf water, lemon fruit extract, and sage extract that match the product's name, plus panthenol for strand support
• Dual sulfate-surfactant system creates a fuller lather that helps fine hair look and feel thicker
• Designed as part of a matched system — Paul Mitchell recommends pairing it with the Lemon Sage Thickening Conditioner

Cons:

• Formulated with sulfate surfactants rather than a color-safe base, so color-treated hair may fade faster with regular use than it would with a sulfate-free shampoo
• Contains methylchloroisothiazolinone and methylisothiazolinone preservatives, recognized potential sensitizers for some scalps
• Several named fragrance components (linalool, limonene, hexyl cinnamal) are common fragrance allergens worth knowing about for sensitive skin
