Gentle sebum-regulating, purifying anti-dandruff shampoo / 6.76 oz

Biofficina Toscana’s Purifying Anti-dandruff Shampoo has been specifically formulated to have sebum-regulating and purifying effects on the scalp. With its base of plant-based surfactants to gently (but effectively) cleanse scalp and hair, it avoids the overly stripping experience of many purifying shampoos. Instead, a smart blend of botanical extracts (burdock, ivy, juniper, and birch) provides oil-regulating oomph, and Venus Hair Fern extract adds purifying properties that have been linked to prevention of hair loss.

But what takes this formula to the next level is piroctone olamine, an ingredient that not only treats the itchiness associated with dandruff, but also its frequent root cause — a naturally occurring fungus called Malassezia globosa that is present on everyone's scalp, but causes irritation and flaking on scalps that are sensitive to it. (Sort of like the pesky demodex mites that are commonly associated with rosacea on skin.)

Like Biofficina Toscana's Gentle Shampoo Concentrate, it’s an eco-friendly concentrate that can be either used as is or diluted with water. Alternatively, you can personalize it with a Hydrolat of your choice for even more supercharged scalp benefits. Here's a breakdown of the Hydrolats you can choose from:

- Lavender for scalps of any type, especially sensitive (also works beautifully sprayed on between shampoos for a purifying scalp massage)

- Rosemary to rebalance oily scalps and fight dandruff

- Sage to fight scalp acne, balance oil production, fight perspiration, and boost volume — it's also Biofficina Toscana's top pick for thinning hair

- Cypress to soothe dry, itchy/flaky scalps and restore vitality to dry, damaged hair

To get the perfect dilution level, order Biofficina Toscana’s My Shampoo bottle, too. Highly recommended for those of us who consider ourselves Type A.
