How to prevent hair loss after bariatric surgery (without stressing out)

Do you look in the mirror and see more hair in the brush than before? You are not alone, and there is a solution. Here we tell you how.

How to prevent hair loss after bariatric surgery (without stressing out)?

Hair loss after bariatric surgery is more common than you think, and although it may feel alarming, it is temporary and reversible if you act in time.

You are not losing your progress nor are you doing anything wrong. Your body is simply readjusting to a new way of nourishing itself, and the hair —as a reflection of internal health— may be the first to show signs.

Why does hair fall out after surgery?

There are several reasons, but the most common combination is:

• Rapid weight loss

• Protein deficiency

• Low in key nutrients (biotin, zinc, iron, B12)

• Physical and emotional stress

This hair loss is called telogen effluvium, and it usually appears between the third and sixth month post-surgery. The good news: it is temporary, if properly addressed.

Key nutrients to strengthen your hair from the inside

Your new digestive system absorbs differently. That’s why it’s important to focus on supplements that have adequate doses, high absorption, and bariatric support.

1. Protein

Hair is made of keratin, a protein. If you do not consume enough daily protein, your body stops prioritizing hair growth.

• Goal: at least 60–80g per day, according to your plan.

• Recommendation: high-quality protein powder to supplement if you don't reach it with food.

2. Biotin

Helps hair growth and strengthens nails and skin. It is better absorbed in liquid forms or soft capsules.

• Recommendation: at least 5,000 mcg per day.

3. Zinc

Regulates follicle growth and prevents hair thinning. Its deficiency is very common post-surgery.

• Tip: look for bariatric multivitamins that already include it.

4. Iron

Without enough iron, oxygen does not reach the hair follicle. If you are a woman and still menstruate, this point is vital.

• Ideal: Iron Soft (chewable iron), which absorbs better and does not cause constipation.

5. Vitamin B12

Key for cell regeneration, energy, and metabolism. Without it, not only does hair fall out: mood also drops.

• Suggested dosage: 500–1,000 mcg sublingual or high-absorption capsule.
