Why does Mounjaro and rapid weight loss cause hair loss?

Rapid weight loss from medications like Mounjaro, Ozempic, or Wegovy triggers a condition called telogen effluvium. When your body experiences sudden nutritional changes or stress from rapid weight loss (typically 1-2 stone or more), your hair follicles enter a resting phase and shed. This usually begins 2-4 months after starting the medication or weight loss journey. The good news: it's temporary. Your hair will recover, but it can take 9-12 months.

Will extensions damage my already fragile hair?

Not if done correctly. We exclusively use ultra-lightweight keratin bonds for clients experiencing weight loss-related hair loss. These bonds are 60% lighter than traditional methods and distribute weight evenly across your hair. We assess every client's hair strength during consultation and may recommend waiting if hair is too fragile, or fitting fewer extensions with specific placement to protect your natural hair during its recovery phase.

How soon after noticing hair loss can I get extensions?

We can fit extensions as soon as you notice thinning, provided your remaining hair has adequate strength and density. During your free consultation, we'll examine your hair's condition, check for active shedding, and determine if immediate fitting is suitable or if waiting 4-8 weeks would be better. Every case is different - some clients are ready immediately, others benefit from waiting until shedding slows.

How long will I need extensions for?

Most clients with Mounjaro or weight loss-related hair loss need extensions for 9-12 months - the time it takes for your natural hair to fully recover and regrow. Your extensions can be maintained through this period with refits every 10-12 weeks. As your hair recovers, we gradually reduce the number of bonds fitted until your natural hair has returned to its pre-weight loss density and you no longer need them.

What if my hair continues to shed after getting extensions?

If shedding continues after fitting, we monitor your hair closely at each maintenance appointment. We can reduce the number of bonds, reposition them to less affected areas, or recommend a temporary removal until shedding stabilises. Your hair health always comes first. We'll work with you throughout your recovery journey, adjusting our approach as your hair changes.

Can extensions help my hair look normal again while I'm losing weight?

Absolutely. That's precisely what they're for. Extensions give you back your confidence and normal appearance while your body adjusts to weight loss and your hair recovers naturally. You can continue your weight loss journey without the emotional impact of visible hair thinning. Many clients say extensions helped them stay motivated with their health goals because they didn't have to sacrifice their appearance during the process.

Understanding Weight Loss Hair Loss (Telogen Effluvium)

Why Rapid Weight Loss Causes Hair Shedding

Medications like Mounjaro (tirzepatide), Ozempic (semaglutide), and Wegovy (semaglutide) enable rapid weight loss - typically 1-2 stone or more within a few months. This triggers a stress response in your body called telogen effluvium, where hair follicles enter a resting phase and shed 2-4 months later. It's not the medication itself causing hair loss - it's the rapid weight change your body experiences.

The Good News: Recovery & Solutions

Your hair will recover naturally over 9-12 months as your body adjusts and hair cycles reset. During this recovery period, our ultra-lightweight keratin bond extensions provide confidence and coverage without stressing your fragile, recovering hair. We use fewer bonds, strategic placement, and the gentlest methods available specifically designed for hair weakened by rapid weight loss.
