Is Mounjaro Making Your Hair Fall Out?
Mounjaro and Hair Loss: How Zappas Salons Can Help
Starting Mounjaro or another GLP-1 treatment can be a positive step towards improving your health, wellbeing and confidence.
However, some people notice increased hair shedding during significant weight loss. Your hair may feel thinner, your parting may look wider or you may see more hair than usual in your brush or shower. This can be worrying, but it does not always mean the hair loss is permanent.
At Zappas Salons, there is no judgement about your health, weight loss or treatment choices. Our expert team can assess your hair and scalp and recommend professional treatments, supplements and homecare to support its condition and appearance.
Mounjaro Hair Loss: Key Facts
- Hair shedding has been reported by some people taking Mounjaro and other GLP-1 treatments.
- Rapid weight loss, eating less, nutritional gaps and physical stress may contribute.
- A common cause is telogen effluvium, which is usually temporary.
- Shedding often begins two to three months after the original trigger.
- Do not change prescribed medication without speaking to your healthcare provider.
- Zappas offers complimentary Kérastase K-SCAN analysis, Nioxin treatments, Kérastase Genesis homecare, Glowwa supplements and expert salon advice.
Does Mounjaro Cause Hair Loss?
Hair loss is a possible side effect of Mounjaro, although the medication may not be the only cause. A reduced appetite can make it harder to obtain enough protein, iron, zinc and other nutrients needed for healthy hair. Rapid weight loss can also temporarily disrupt the natural hair-growth cycle.
For many people, shedding may be influenced by a combination of weight loss, nutrition, hormones, stress and general health.

Telogen Effluvium After Weight Loss
Telogen effluvium is a common form of widespread, usually temporary shedding. It happens when more hairs than usual enter the resting stage at the same time. Shedding often appears two to three months after the original trigger.
Common signs include reduced volume, more hair in the shower or brush and increased scalp visibility through the parting. In many cases, the follicles remain healthy and capable of producing new hair, although recovery takes time.
Should You Stop Taking Mounjaro?
Do not stop or change prescribed medication without speaking to your doctor, pharmacist or prescribing healthcare provider. They may review your diet, symptoms and rate of weight loss or recommend blood tests to check for concerns such as iron deficiency or thyroid problems.
Salon treatments can support your hair and scalp, but they do not replace medical advice.
Hair Loss and Scalp Care at Zappas
Hair shedding can affect your confidence as well as your appearance. At Zappas, we can assess the visible condition of your hair and scalp before recommending suitable treatments, products, cuts and colour services.
Our aim is to help your existing hair feel stronger, look fuller and remain in the best possible condition while your body adjusts.

Complimentary Kérastase K-SCAN Scalp Analysis
Zappas offers complimentary Kérastase K-SCAN scalp and hair analysis across its salons. K-SCAN uses a smart camera to examine the scalp and hair fibre in detail. It can highlight visible concerns such as dryness, oiliness, product build-up and changes to the condition of the hair.
Your stylist can then create a more personalised salon treatment and homecare plan.
Nioxin Scalp Treatments for Thinning Hair
Nioxin is a specialist scalp and haircare range created for women and men experiencing thinning hair. Professional Nioxin treatments help deeply cleanse and refresh the scalp, removing excess oils and product build-up while creating the best possible environment for healthier-looking hair.
Nioxin can also help strengthen fragile strands, reduce breakage and improve the appearance of hair thickness and density.
Your Zappas stylist can recommend the most suitable in-salon treatment and Nioxin homecare system based on whether your hair is natural or colour-treated and the level of thinning you are experiencing.

Kérastase Treatments and Genesis Homecare
Following your K-SCAN analysis, your stylist may recommend a personalised Kérastase treatment such as Fusio-Dose. This can target concerns including weakness, dryness, dullness and poor manageability.
For use between appointments, Kérastase Genesis is designed for weakened hair prone to falling through breakage. The range includes shampoos, conditioners, masks and scalp serums. Genesis does not treat a medical cause of hair loss, but it can strengthen vulnerable hair and reduce avoidable breakage that makes thinning appear more noticeable.
Glowwa Hair Supplements at Zappas
Healthy hair also needs support from within. When Mounjaro reduces your appetite, it may become harder to consistently obtain all the nutrients your hair needs. A targeted supplement can therefore support your wider haircare routine.
Zappas stocks the Glowwa Hair Food range, including formulas for general hair support, menopause and for men. Glowwa contains nutrients including biotin and zinc, which contribute to the maintenance of normal hair. Your stylist can explain the different options and help you choose the most suitable formula.

L’Oréal Professionnel Colour for Fragile Hair
Hair shedding does not always mean you must stop colouring your hair. Zappas uses high-quality L’Oréal Professionnel hair colour across all six salons. Your colourist will assess your hair before recommending the most suitable approach.
This may include reducing repeated lightening, avoiding unnecessary colour overlap or choosing a softer, lower-maintenance technique. Carefully positioned colour can also help fine hair appear fuller.
The aim is to create a beautiful result while protecting the strength and condition of your hair.
Haircuts and Homecare for Thinning Hair
The right haircut can make finer hair look fuller and stronger. Removing thin ends, creating a solid outline and avoiding excessive layering can improve the appearance of density.
Your stylist can also recommend professional Nioxin or Kérastase products for your hair and scalp, alongside techniques that create volume without excessive heat or tension.
Personalised advice helps you avoid products that are too heavy, harsh or unsuitable for your changing hair.
A Complete Hair and Scalp Plan
There is rarely one single solution for hair shedding. Your personalised Zappas plan may combine K-SCAN analysis, Nioxin scalp treatments, Kérastase salon care, Genesis homecare, Glowwa supplements and an expertly planned cut or L’Oréal Professionnel colour service.
This is not about promising an overnight transformation. It is about providing consistent, professional support for your scalp, hair and confidence.
