Just as with facial cosmetics, where nighttime is the key moment for the skin to receive the most restorative treatments, while we sleep, **hair** becomes **more receptive**, free from external aggressions and prepared to regenerate in depth.

To harness all this potential, Montibello presents hop Ultra Repair Overnight Serum, a new leave-in treatment that transforms nighttime rest into a true holistic hair care ritual. The result: waking up with visibly stronger, softer, and more luminous hair

The way we care for our hair is evolving towards simpler, but much more effective routines. Overnight care allows for the incorporation of high-performance treatments during a calm moment, effortlessly and without adding time to the daily routine.”, explains Mayte Garrote, director of the hair salon Different Estilistas in Zamora.

Intensive repair during rest

The body enters repair mode: cortisol decreases, regenerative activity increases, and cellular renewal processes are optimized. Although hair is an inert fiber, the scalp and hair follicle do respond to the biological clock. In fact:

  • Scalp blood flow improves during rest, facilitating nutrient delivery.
  • Skin permeability increases, which favors the absorption of active ingredients.
  • Cellular synthesis in the follicle is activated, key for stronger and more balanced growth.

Therefore, overnight treatments are formulated to work in sync with that biological rhythm: they act for hours, without external interference, when the hair and scalp are most receptive.

High-performance hair care powered by bioscience

The technology behind this innovation, LifeAlgae Bioscience, is an algae biotechnological complex obtained through an exclusive hyperfermentation process, which quadruples the potency of active molecules. This system acts on both the scalp and the hair fiber, offering professional results from the first application.

The formula is completed with vegan collagen, the most trending anti-aging ingredient in overnight treatments. This powerful active ingredient plumps, strengthens, repairs, and restores the hair fiber, improving its elasticity, softness, and shine, while protecting it from breakage.

How to Apply Hop Ultra Repair Overnight Serum?

Its application is very simple: 1–3 pumps on mid-lengths and ends, on dry or damp hair, before sleeping, 2–3 times a week. It does not require rinsing in the morning and is suitable for all hair types. A simple gesture that provides 8 hours of intense nourishment and overnight protection.

“At night, hair is free from external aggressions and much more receptive to active ingredients. This serum, as it doesn't require rinsing, adapts to the real pace of daily life and allows you to wake up with repaired and ready hair, all with no extra effort,” explains Christian Vendrell, director of the hair salon Identity Peluqueros, in Valencia.
