When night falls and the world slows down, the most intimate moment of self-care begins. Sleeping is no longer just about resting: it is about reconnecting, regenerating and letting beauty work in your favour. Just as in facial skincare, where night-time is the key moment for the skin to receive the most repairing treatments, while we sleep the hair becomes more receptive, free from external aggressors and ready to regenerate deeply. To harness this full potential, Montibello presents hop Ultra Repair Overnight Serum, a new leave-in night serum that turns nightly rest into a true holistic haircare ritual. The result: waking up with hair that is visibly stronger, softer and more luminous.
“The way we care for hair is evolving towards simpler routines that are far more effective. Night-time care allows high-performance treatments to be incorporated at a moment of calm, effortlessly and without adding extra time to the daily routine,” explains Mayte Garrote, director of the hair salon Different Estilistas in Zamora.
Intensive repair while you sleep
Did you know that circadian cycles directly influence the effectiveness of the treatments we receive? During the night, the body enters repair mode: cortisol levels decrease, regenerative activity increases and cellular renewal processes are optimised. Although hair is an inert fibre, the scalp and hair follicle do respond to the biological clock. In fact:
-
Blood flow to the scalp improves during rest, facilitating the delivery of nutrients.
-
Skin permeability increases, enhancing the absorption of active ingredients.
-
Cellular synthesis in the follicle is activated, which is key to stronger, more balanced growth.
For this reason, night treatments are formulated to work in harmony with this biological rhythm: they act for hours, without external interference, when hair and scalp are most receptive.
High-performance haircare driven by bioscience
The technology behind this innovation, LifeAlgae Bioscience, is a biotechnological algae complex obtained through an exclusive hyperfermentation process that quadruples the potency of active molecules. This system acts on both the scalp and the hair fibre, delivering professional results from the very first application.
The formula is completed with vegan collagen, the most on-trend anti-ageing ingredient in night treatments. This powerful active ingredient fills, strengthens, repairs and restores the fibre, improving elasticity, softness and shine, while protecting the hair against breakage.

How to apply Hop Ultra Repair Overnight Serum
Application is very simple: apply 1–3 pumps to mid-lengths and ends, on dry or damp hair, before going to bed, 2–3 times a week. No rinsing is required in the morning and it is suitable for all hair types. A simple gesture that delivers 8 hours of intense nourishment and overnight protection.
“During the night, hair is free from external aggressions and much more receptive to active ingredients. This night serum, which requires no rinsing, adapts to the real rhythm of everyday life and allows you to wake up with repaired, ready-to-go hair, all without any extra effort,” says Christian Vendrell, director of the hair salon Identity Peluqueros in Valencia.
