Taula de Continguts
Hydrafacial Keravive is a non-invasive scalp treatment that, according to the manufacturer, cleanses with gentle suction and exfoliation, delivers peptides and hydration, and is completed with a spray you use daily at home. It is a way to look after the skin under your hair in the same way you look after the skin on your face; it is not a treatment for alopecia. In this guide we explain what each phase involves, what you can and cannot expect, when it is better to wait, how it differs from medical hair treatments and how we approach it at Santé Madrid.
Key points
- The scalp is skin: it has its own barrier, produces sebum and can become dry, irritated or build up product residue.
- According to the manufacturer, Keravive is organised into three phases: purify with gentle suction and exfoliation, nourish with peptides and hydration, and maintain at home with a peptide spray.
- Its aim is to cleanse and hydrate the scalp. The manufacturer describes hair that looks fuller in its own studies; results vary from person to person.
- If what worries you is hair loss, the first step is a medical consultation (€50) to assess the cause of the hair loss.
- Hair mesotherapy, PRP and exosomes are medical treatments that the medical team decides on after a diagnosis.
Your scalp is skin too
We tend to spend time on the skin of our face and forget the skin under our hair. Yet the scalp is skin: it has a horny layer that acts as a barrier, sebaceous glands and its own ecosystem of microorganisms. A recent review on hair ageing explains that scalp care has moved from focusing only on dandruff to applying the logic and actives of skincare, and that the resilience of the scalp barrier is important in preventing flaking and itching (Westgate and colleagues, 2025).
The same review notes that sebum production changes with hormones and with age, for example with menopause, and that these changes affect the condition of the scalp. The manufacturer of Keravive adds that when the scalp is not properly cleansed and nourished, itching or flaking can appear, and it lists among the factors that can play a role post-partum stress, hormonal imbalances, chemical damage from hair dye or other treatments and build-up from styling products (HydraFacial Keravive).
That is why it makes sense to care for the scalp as part of your skin. That said, itching, flaking or redness that does not settle can also be the sign of a condition that should be assessed before you think about any aesthetic treatment.
What Keravive is and what a session involves
Keravive is the HydraFacial line dedicated to the scalp; on its website, the manufacturer now presents it as HydraScalp with Keravive. It describes it as a non-invasive, peptide-based treatment organised into three phases (HydraFacial Keravive).
1. Purify. Gentle suction and exfoliation cleanse the scalp and, according to the manufacturer, stimulate and open the follicles.
2. Nourish. Peptides and hydration are infused into the freshly cleansed follicles and the surrounding skin. Among the ingredients, the manufacturer lists niacinamide, its own peptide complex, vitamin B5 and arginine.
3. Maintain at home. The manufacturer includes a peptide spray to use daily at home between sessions, and presents that daily use as part of the treatment.
According to the manufacturer, the professional can choose a partial or a full-scalp application, and the treatment is designed for different hair types, including dyed hair, braids and extensions. It also states that it is usually planned as a series of monthly sessions rather than a one-off session. At Santé, the area, the number of sessions and how often they take place are decided after the assessment.
What it is for and what you cannot expect
The aim of Keravive is scalp care: removing residue, exfoliating gently and hydrating. It is aesthetic care and we treat it as such.
The manufacturer cites its own clinical studies from 2019, one of them described as a pilot, in which participants reported hair that looked fuller and shinier, and a smoother scalp with less itching after one or several sessions combined with the home spray (HydraFacial Keravive). These are the company's own data, based on what participants reported, and in our search we did not find independent studies on Keravive published in PubMed. That is why we treat them with caution: results vary from person to person and we make no promises about hair density or growth.
What Keravive is not: it is not a treatment for alopecia and it does not replace a diagnosis of hair loss. The review cited above points out that most cases of hair loss usually have a clinical diagnosis and an explanation, and that the specialist aims to address the underlying condition and lifestyle factors. It also notes that sudden stress, some physiological events or certain medicines can trigger heavy shedding (Westgate and colleagues, 2025). If you notice that you are losing more hair, that you have less density or areas where more of your scalp shows, the right place to start is a medical consultation.
Keravive compared with medical hair treatments
At Santé Madrid we work with Keravive and, separately, with medical hair treatments: hair mesotherapy, hair PRP and hair exosomes, which are indicated after a medical consultation. They have different aims: this table summarises the role of each option and who decides whether it is indicated.
| Option | Aim | When it is considered | Who decides |
|---|---|---|---|
| Keravive | Cleansing and hydrating the scalp; according to the manufacturer, hair that looks fuller | A tight scalp, product residue or dull-looking hair, with no hair loss to investigate | The medical team, after the assessment |
| Medical consultation | Finding the cause of hair loss or loss of density | Whenever what worries you is hair loss | The doctor, during the consultation itself |
| Hair mesotherapy, PRP or exosomes | Medical treatments considered for hair loss or loss of density | After the medical consultation, if they are indicated | The medical team, after the diagnosis |
Keravive can sit alongside a medical hair treatment: the manufacturer states that your provider may recommend it to complement other hair or scalp treatments. But the order matters: first the diagnosis, then the medical treatment if it is indicated and, if it fits, scalp care. This article does not go into how those medical treatments are performed; whether they are indicated is explained in the consultation, depending on your case.
When to wait or check with us first
Keravive is considered for a scalp without lesions, with mild issues such as a feeling of tightness, product residue or dull-looking hair. There are situations in which we prefer to assess first and, sometimes, postpone the session or choose another option.
In all of these cases, mention it during the consultation. The medical team will decide whether it is better to wait, adapt the treatment or refer you to a dermatologist when the cause requires it. When the scalp is irritated, exfoliation may not be appropriate at that moment, even if it is gentle.
Sun, dry air and heating: the scalp in the city
Madrid's climate is usually described as continental and dry, with sunny summers and cold winters when the heating tends to be on. Like the skin on your face, your scalp can feel that context: in general, dry air can contribute to a feeling of tightness or flaking, and the sun can affect above all the areas where hair is finer or the parting is exposed.
The review by Westgate and colleagues lists ultraviolet radiation and pollution among the environmental factors that can promote oxidative stress and micro-inflammation in tissues such as the scalp. It also cites ultraviolet radiation, pollution, chemicals, styling appliances and heat among the main factors in the ageing of the hair fibre (Westgate and colleagues, 2025).
None of this turns Keravive into a form of protection. The basics are still daily: washing your hair with a suitable shampoo, rinsing out product residue properly, protecting your head from the sun with a hat or cap in summer and not overusing straighteners and hairdryers at maximum temperature. Keravive can be considered as occasional care within that routine, for example after the summer or in the middle of winter, if the team considers it appropriate. Results vary from person to person.
How we work at Santé Madrid
Santé Clinics Madrid is at C. de Amador de los Ríos, 1, Chamberí, 28010 Madrid. We are open Monday to Friday from 9:00 to 21:00 and on Saturdays from 10:00 to 15:00; the clinic is closed on Sundays.
If your goal is scalp care, you can start with a free aesthetic consultation with a Beauty Coach, in which we review your routine, the products you use and what you notice on your scalp. If what worries you is hair loss or loss of density, the path is different: a medical consultation, priced at €50, in which the medical team assesses the cause of the hair loss and decides whether any medical treatment is indicated.
Keravive is part of the HydraFacial family we work with at the clinic; if you are interested in the facial protocols, we explain them in our guide to HydraFacial in Madrid. During your Keravive session we explain each phase and adapt the treatment to your scalp. It is performed by the Santé Madrid medical team after the assessment, and we make no promises about results: results vary from person to person.
Frequently asked questions

How is it different from hair mesotherapy, PRP or exosomes?
Keravive is non-invasive scalp care focused on cleansing and hydration. Hair mesotherapy, PRP and exosomes are medical treatments that are considered after a diagnosis, if the doctor recommends them.
Does Keravive hurt?
The manufacturer describes it as a non-invasive, relaxing treatment. How it feels varies from person to person; if anything bothers you, you can tell us during the session.
How many sessions are needed?
According to the manufacturer, it is usually planned as a series of monthly sessions, with a spray used daily at home in between. In your case, the number and frequency are set after the assessment.
Do I need to use anything at home?
According to the manufacturer, the treatment includes a peptide spray for daily use at home. If Keravive is right for you, we explain how to use it.
Can I have it if my hair is dyed or I wear extensions?
The manufacturer states that it is designed for different hair types, including dyed hair, braids and extensions. Even so, we discuss it in the consultation so we can adapt the session.
What if I have psoriasis or dermatitis on my scalp?
If you are in an active flare or have lesions in the area, we assess it in a consultation first. The medical team will decide whether it is better to wait, adapt the treatment or refer you to a dermatologist.
If your scalp feels tight, has product residue or your hair looks dull, a consultation at Santé Madrid will help you find out whether Keravive is right for you. And if what worries you is hair loss, we will start by understanding the cause before talking about treatments.
