In-Residencia Hydrating Shampoo
A Gorgeous, Silky Balancing Cleanse
LOS DETAILS
Fragrance-Free | 310mL - 10.5 fl oz
A gorgeous, silky balancing cleanse.
This microbiome-friendly shampoo is rich in weightless, hydrating actives that nourish both scalp and strands. It gently lifts away daily buildup — think oil, dirt, and pollution — without disrupting your skin’s delicate balance.
Finally, a luxurious lather without the usual suspects: no fragrance, no essential oils, no irritation. Instead, you'll find meticulously chosen, scientifically proven, ingredients like Fermented Probiotics, Cationic Hyaluronic Acid, and Panthenol (Vitamin B5), expertly layered to cleanse, hydrate, and support the scalp’s barrier function.
Designed for sensitive skin and sensitive souls alike, it leaves your hair feeling light, fresh, and beautifully cared for.

"My hair takes forever to wash, so I usually only do it once a week - and when I do, I double cleanse. But even with our gentle shampoo, that’s not always necessary - feel free to tailor it to your routine. If you wash more frequently, a single cleanse might be plenty!"
CATALINA'S NOTA
Not Just The Tip
This shampoo’s real job is to cleanse and balance the scalp - where oil, product buildup, and irritation often build up. Focus on the roots, allowing the lather to gently rinse through to the ends. This helps keep your lengths hydrated and healthy while giving your scalp the refresh it needs.
CATALINA'S NOTA
Better Together
Our shampoo and conditioner are designed to work in harmony - while the shampoo gently cleanses without stripping, the conditioner locks in hydration, supports the scalp barrier, and seals the cuticle for smoother, shinier strands.
