Lavender, Bergamot and Black Pepper Essential Oils
Our beloved Thea scent, now as a deeply hydrating conditioner bar — grounding, gently floral, and subtly spiced, with a clean, comforting finish that leaves your hair soft, smooth, and beautifully scented.
This bar is carefully formulated with rich botanical butters, plant-based conditioning agents, and a pH-balanced, silicone-free base to nourish, protect, and detangle without weighing hair down. Shea and cocoa butters moisturise and smooth, while avocado oil adds lightweight shine and softness.
- Lavender soothes the scalp
- Bergamot enhances shine
- Black Pepper stimulates circulation
With no added colourants, the bar melts into hair under warm running water, releasing a silky texture that glides through the lengths with ease. Pairs beautifully with the Thea shampoo bar for a complete, natural haircare ritual.

Why Switch to Solid Haircare?
Solid shampoo and conditioner bars are a gentle, low-waste alternative to bottled products. Free from harsh detergents, silicones, and plastic packaging, they’re better for your hair and the planet. Each bar is long-lasting, travel-friendly, and full of natural, plant-based ingredients.

How to Use
Wet your hair and warm the bar under running water. For shampoo, lather in your hands or glide directly over your scalp. For conditioner, stroke onto the ends and let it melt in. Rinse thoroughly and store the bar somewhere dry between uses.
