Scalp feels more comfortable from the very first application
Scalp feels less reactive
We recommend René Furterer Astera Sensitive High Tolerance Shampoo for clients with sensitive, reactive, or easily uncomfortable scalps who need a gentle daily cleanser.
This is a beautiful option when the scalp feels tight, delicate, or easily irritated by traditional shampoos. Massage gently rather than aggressively, and rinse thoroughly. For sensitive scalps, we recommend keeping the routine simple and avoiding frequent layering of stimulating or heavily fragranced scalp products unless recommended by a professional.
