The conditioner half of Dr.Groot's Bio Exosome line, designed to do something most conditioners aren't — work on the scalp, not just the lengths. While a typical conditioner stays away from the roots to avoid weighing hair down, this one is built around bio-exosome technology to deliver regenerative actives directly where the hair grows from. Massage it into the scalp and through the ends, leave it for a couple of minutes, then rinse.

The formula carries the same scalp-care actives as the shampoo — salicylic acid, niacinamide, and panthenol — plus encapsulated biotin and 17 amino acids to strengthen each strand from the inside. A blend of botanical oils softens the lengths without coating them in silicones, so hair feels light and clean, never greasy at the roots. Pair with the matching shampoo for the full system, or use solo if you want to upgrade just one step.

Best For: Thinning hair, sensitive or irritated scalps, and anyone who wants a conditioner that strengthens from the root rather than just smoothing the ends.
