Why do some people notice hair loss after significant weight loss?

Hair loss after significant weight loss is often related to a condition called telogen effluvium. This happens when the body experiences physical stress or rapid changes, which could be due to reasons such as calorie restriction, hormonal shifts, or nutrient deficiencies.

Is the hair loss some people notice during their weight loss journeys temporary?

In most cases it should be. Once the body adapts to your new weight and your nutritional balance is restored, hair growth usually resumes within several months.

However, if restrictive dieting continues or underlying deficiencies aren’t addressed, hair loss can continue to happen.

What role can nutrition play in maintaining healthy hair during weight loss?

Nutrition plays a central role. Hair is made primarily of a protein called keratin, so getting enough protein through the foods you eat is key.

Iron, zinc, selenium, B vitamins, vitamin D, and omega-3 fatty acids also support healthy hair growth. Balanced meals that include lean proteins, whole grains, fruits, vegetables, and healthy fats can make a big difference.

Can medicated weight loss treatments cause hair thinning or hair loss?

Some medications can lead to temporary hair shedding. However, each medication works differently, so it’s important to talk to your healthcare provider if you notice excessive hair shedding while on treatment.

Are there warning signs that hair loss is more than just a temporary reaction to dieting and medication?

Yes. If hair loss continues for more than six months after reaching your target weight, or if you notice patchy bald spots, scalp irritation, or changes in hair texture, it’s worth consulting a dermatologist or healthcare provider. These signs may indicate another underlying condition.

What’s your advice for people who are worried about losing hair while trying to lose weight?

Focus on gradual, balanced weight loss. Extreme calorie restriction or cutting out entire food groups can affect your nutrient balance. So, ensuring that you’re getting enough protein and micronutrients and considering taking a high-quality multivitamin can also help. Talking to your doctor or a nutritionist can help if you’re unsure of where to start to food management.

Managing stress and getting enough sleep also play a surprisingly big role in preventing hair shedding. Your wellbeing matters in maintaining a healthy body.

Using a product like the Scandinavian Biolabs Serum will ensure your hair is kept in the growth phase and optimise all ongoing growth.
