Chemo Curls: What to Expect When Your Hair Grows Back
When you finish chemotherapy, one of the first signs of recovery is your hair starting to grow back. For many people, this new hair doesn’t look or feel the same as it did before treatment. In fact, it may grow back curly—even if it was straight before. These changes are often called “chemo curls.”
Why Does Hair Grow Back Curly After Chemo?
Hair texture comes from the shape of the hair follicle under your skin. Chemotherapy affects rapidly growing cells, including the ones that form your hair. This can temporarily change how the follicles produce hair. As a result, new hair may come in curly, wavy, thinner, or even a different color.
The exact reason for chemo curls isn’t fully understood, but doctors believe it’s caused by the way chemotherapy affects the hair follicles as they heal and restart hair growth.
Will Chemo Curls Last Forever?
Not necessarily. For some people, the curls are temporary. As the hair grows longer and the follicles fully recover, it might return to its original texture within six months to a year. For others, the curls may stay longer—or even become a new normal. Everyone’s body reacts differently, so there’s no one-size-fits-all answer.
Tips for Caring for Chemo Curls
If you’re new to managing curly hair, here are some helpful tips to keep your regrowth healthy and looking great:
Use Curl-Friendly Products
Mousse helps define and hold bouncy curls.
Curl creams or puddings give you softer, more relaxed waves.
Leave-in conditioner keeps hair moisturized and can enhance fuller curls.
Dry Gently with a Diffuser
If you use a blow dryer, attach a diffuser and use it on low heat. This helps prevent frizz and protects your scalp, which might still be sensitive after chemo.Avoid Heat and Chemicals at First
Don’t use curling irons, flat irons, dyes, or relaxers for at least six months after your hair starts growing back. Your new hair is delicate, and it needs time to strengthen.Change Your Washing Routine
Curly hair tends to be drier than straight hair because natural oils can’t travel down the curls as easily.
Try washing your hair less often—every two to three days instead of every day.
You can also try co-washing, which means using just conditioner without shampoo. This helps keep moisture in your hair.
Be Kind to Yourself
Hair regrowth can be an emotional experience. While some people feel happy and hopeful when their hair comes back, others may feel surprised or even upset by how different it looks. That’s completely normal.
It’s also common for people around you to assume that regrowth means you’re “back to normal.” But your healing journey is personal—and it takes time. It’s okay to feel a mix of emotions during this stage.
Remember: your hair doesn’t define your strength. Whether it’s curly, straight, short, or long, it tells a story of resilience.
A Quick Summary
Chemo curls are common after treatment due to changes in the hair follicles.
The curls may be temporary or long-lasting—everyone’s journey is different.
Take care of new hair gently, using moisturizing products and avoiding heat or harsh chemicals.
Wash less often, and try co-washing to keep curls soft and hydrated.
It’s okay to feel a wide range of emotions during this time—support is available if you need it.
Final Thoughts
Getting your hair back is a powerful sign of healing. And even though chemo curls may not look like the “old you,” they’re a beautiful reminder of how far you’ve come. Be patient with yourself, explore what works for your new hair, and most importantly—celebrate the strength that carried you through.
