Losing weight can spur significant hair shedding for some people. But there are steps you can take to help minimize hair loss when trying to slim down.

How to Prevent Hair Loss During Weight Loss

Strategies to reduce hair shedding when losing weight include eating adequate protein, maintaining key nutrient levels with supplements, avoiding crash or fad diets, incorporating scalp massages, using biotin and collagen supplements, and being gentle when washing, brushing and styling hair.

Eat Sufficient Protein

Consuming 0.5-1 gram of protein per pound of body weight provides the amino acids hair needs to grow. Include lean meats, eggs, nuts, beans, and low-fat dairy.

Address Nutrient Deficiencies

Check levels of iron, zinc, vitamin D, vitamin B12, and omega-3s. Supplement if low or deficient to nourish follicles.

Avoid Extreme Diets

Crash diets, very low calorie plans, or severely limiting nutrients stresses the body and disrupts the hair growth cycle.

Scalp Massages

Gently massaging the scalp 2-3 times per week boosts circulation to hair follicles.

Take Biotin and Collagen

Biotin and collagen supplements support keratin production for stronger strands less prone to breakage.

Why Does Hair Loss Happen with Weight Loss?

Common causes include:

  • Caloric restriction
  • Nutritional deficits
  • Low protein intake
  • Hormonal changes
  • Body stress
This can shift more hair follicles into the shedding phase.

Will My Hair Recover?

For most people, the hair loss is temporary. Hair regrowth usually returns to normal once weight stabilizes and nutrition is balanced again.

Tips for Healthy Hair Maintenance

Additional tips include:

  • Avoid tight hairstyles that stress follicles
  • Use wider-tooth combs
  • Limit heat styling
  • Gently detangle hair when wet
  • Reduce chemical processing

Minoxidil for Weight Loss Hair Loss

Using over-the-counter 5% minoxidil can help override the hair loss signals until the shedding phase passes.

See a Doctor if Shedding Persists

Consult a doctor if shedding remains excessive after weight loss efforts end. Get bloodwork to check for underlying issues and possible treatment options.

The Bottom Line

Adequate protein, nutrients, scalp circulation, and gentle haircare reduces hair shedding during weight loss. But see a doctor if hair loss remains significant after weight stabilizes.
