Taking Mounjaro? Dermatologist Explains How The Drug Affects Your Hair And Skin

Weight-loss medications like Mounjaro are becoming more common, especially among people trying to manage obesity, diabetes, or stubborn weight gain. While many people focus on the number on the scale, experts say it is equally important to pay attention to what rapid weight loss may do to your skin and hair.

Losing weight too quickly can sometimes lead to side effects like hair fall, dry skin, sagging, or stretch marks – not necessarily because of the medication alone, but because the body is adjusting to sudden changes.

Dermatologist Gurveen Waraich shares an Instagram video talking about the skin and hair care habits people should follow if they are taking – or planning to take – Mounjaro.

Hair Fall Can Happen During Rapid Weight Loss

According to her, hair loss is one of the major concerns people experience during fast weight loss.

The doctor explains that nutrient deficiencies may make the problem worse, which is why it is important to check levels of:

• Vitamin B12
• Vitamin D
• Calcium
• Ferritin

Dr Waraich also stresses the importance of eating enough protein, suggesting around “1 gram per kg body weight per day.”

Protein plays a key role in maintaining hair structure and overall recovery while the body is losing weight.

She also recommends consulting a dermatologist for proper hair supplements instead of self-medicating.

Another important tip? Avoid harsh salon treatments like keratin, cysteine, or smoothing treatments during this phase, as they may cause additional damage to already fragile hair.
