If you apply a serum to your skin, why not to your hair? It also ages, it also needs care: it needs haircare. With You is, precisely, a Spanish haircare brand. Why is Deep Serum different? It is formulated with Vital Oil Plus™, a complex of vegetable oils that deeply moisturizes, regenerates, and protects. Like the rest of With You products, it incorporates SeaComplex, a combination of four algae that hydrate and protect the hair fiber. Interesting, right?
How is it used?
It's the last step in your routine. 1) Breezy Shampoo 2) Sea Glow Instant Mask 3) Soft Shell Conditioner and 4) Deep Serum. If you don't need a lot of hydration, you can skip the mask or conditioner, or replace the conditioner with a leave-in conditioner. Apply it to dry or damp hair.
Who can use it?
It's designed for all hair types and all ages. It is suitable for the curly method. It's for you if you're looking for weightless nourishment and if you want to control frizz. Also if you like original cosmetics.
Its benefits:
- It moisturizes very well and regenerates the hair fiber from the inside. It's authentic haircare.
- It protects against heat from flat irons and hair dryers. Also from sun and pollution.
- It revitalizes and strengthens hair, leaving it softer and shinier.
Sensations?
The clean scent is great, and the hair feels soft and touchable. You'll want to touch it and have it touched. Every day you use it, you'll like it more and more.
