Losing a significant amount of weight can sometimes trigger temporary hair shedding. This occurs because of the stress on the body from rapid weight loss, as well as potential nutrient deficiencies. Luckily, any hair thinning from weight loss is usually reversible.

How to Stop Hair Loss After Weight Loss

To curb hair shedding after losing weight, be sure you're consuming enough protein, iron, zinc and vitamins D and B. Also use gentle hair care practices, apply a hair growth serum, and get scalp massages to stimulate follicles.

Eat Plenty of Protein

Shoot for 0.5-1 gram of protein per pound of body weight daily.

Take a Multivitamin

A multivitamin helps cover any nutritional gaps.

Use Gentle, Volumizing Products

Avoid harsh ingredients that could worsen hair thinning.

Apply a Hair Growth Serum

Serums with caffeine or peptides spur regrowth.

Do Scalp Massages

Massaging the scalp increases blood flow to follicles.

What Causes Hair Loss After Weight Loss

Here are some reasons sudden weight loss can trigger excess shedding:

Stress Hormone Changes

Caloric restriction raises cortisol levels.

Nutritional Deficiencies

Crash dieting depletes nutrients needed for hair growth.

Sudden Drop in Estrogen

Fat cells produce estrogen, which declines as you lose weight.

More Hair is Shed in Anagen Phase

Weight loss shortens the anagen growth phase for more hairs.

Body Shifts Focus

Growth efforts go to vital systems first.

Tips to Minimize Hair Loss from Weight Loss

Follow these tips to safeguard your hair when losing weight:

Lose Weight Gradually

Aim for 1-2 lbs per week to minimize stress.

Eat Plenty of Fruits and Veggies

These provide nutrients for hair health.

Stay Hydrated

Drink the recommended 64 ounces of water daily.

Take Biotin

Biotin supplements strengthen hair against shedding.

Get a Trim

Trimming hair helps remove split ends prone to breakage.

When to See a Doctor

Consult a doctor if you notice:

No Improvement After 1-2 Months

Hair shedding and thinning continues.

Sudden Patches of Hair Loss

Circular bald spots appear on the scalp.

Hair Easily Plucks Out

Hair pulls out by the root with little effort.

Additional Symptoms

Unexplained fatigue, trouble concentrating or insomnia.

The Bottom Line

With a nourishing diet, volumizing products, growth serums and scalp massages, post-weight loss shedding can be reversed. But see your doctor if hair thinning persists despite your best efforts.
