Hair loss after bariatric surgery: How to support fine, thinning hair

After bariatric surgery (such as a sleeve), you may experience more intense and widespread hair loss.

After bariatric surgery (such as a sleeve), you may experience more intense and widespread hair loss. It's not just a cosmetic detail: when the body changes rhythm, hair often shows its signs first—especially if the fiber is already fine and slightly thinning.

The most important part comes before any product: consult with your healthcare team (surgeon/nutritionist/doctor) to monitor any deficiencies and determine the most appropriate supplement. However, your cosmetic routine can do a lot: protect the hair fiber, respect the skin, and support the health of the hair bulb during this delicate time.

The key: don't "pull" your hair, but guide it.

At this stage, the most common mistake is to pursue aggressive solutions ("degreasing" washes, overly vigorous scrubs, hasty movements).

In reality, the opposite is needed:

• Gentle and effective cleansing (to avoid stressing the scalp)
• Structural support (because fine hair breaks more easily)
• Targeted intensive treatment (consistency, not excess)
• ESTĒREL ritual recommended for post-surgery thinning hair

1) Regular cleansing (fine, fragile, sensitized hair)

Phyto Fortifiant Plus

A shampoo designed to gently cleanse and support hair during periods when it appears most vulnerable.

How to use

• Apply and massage gently, without scratching the scalp
• Leave on for a few minutes
• Rinse thoroughly

If necessary, repeat a second application (always using a light method)

2) Thickening and comfort booster (so as not to leave the hair "bare")

Fortifying Milk +: This is the gesture that often immediately changes the perception: tidier, less frayed, more manageable hair - without weighing it down.

How to use it:

• After shampooing, apply it to the lengths and ends (and, if necessary, also lightly to the scalp).
• Comb gently.
• Leave it on for a few minutes and rinse.

3) Intensive Treatment (when hair loss is evident and widespread)

Fortifiante 10 vials: designed as a shock treatment routine during periods when your hair feels "weak" and the loss is more uniform.

How to use it

Apply to the scalp (section by section)

Let it work and proceed to drying

Recommended frequency (practical and sustainable): at least twice a week for 8 weeks, then reassess with us or your hair specialist based on how your scalp responds.

Small touches that make a big difference

• Comb only when necessary and gently (better on damp hair, not soaked).
• Reduce high heat and straighteners: at this stage, the fiber breaks more easily.
• Don't skip washing out of fear: often, the hair that's falling out is already ready to fall out; washing well and gently also helps the scalp feel comfortable.

FAQ

Is hair loss normal after a sleeve treatment?

It can happen: it's a phase many people go through after a major change. The right thing to do is monitor your nutritional status with your medical professional.

Is hair loss permanent?

It's often a transitory phase, but it should be interpreted in context (blood values, diet, stress, predisposition). If you notice rapid worsening or patches/localizations, a dermatological opinion is helpful.

Should I wash less to prevent hair loss?

No: proper cleansing with the right products doesn't "cause" hair loss. Aggressiveness and overly vigorous movements make the difference.

What's the difference between strengthening and "anti-hair loss"?

Strengthening means supporting the hair fiber and its resistance (less breakage, more quality). An anti-hair loss program also works on the scalp and the bulb's vitality phase. In practice: both are necessary.

Can I use conditioners and intensive treatments together during this phase?

Yes: the goal is to avoid leaving the hair shaft fragile and "empty." Conditioner + lotion is a sensible combination if used correctly.

How often should I apply the vials?

As a starting point: twice a week for at least two months. If your skin is very sensitive or reactive, it's best to customize.

What if I also have itchy scalp or dandruff?

Then the routine needs to be revised: first restore balance to the scalp, then work on thickening. In that case, it's best to contact us and we'll establish the correct sequence.

What should I tell my doctor/nutritionist to assess the situation?

Explain that you're experiencing widespread hair loss post-surgery and ask what nutritional check-ups are appropriate for you (they'll decide what's really necessary).
