Losing weight can be an empowering journey, bringing us closer to our health and wellness goals. But for many people, this journey comes with unexpected side effects, including hair loss. 

While shedding pounds, some may notice thinner hair, increased shedding, or even patches of hair loss. If this sounds familiar, you’re not alone – hair loss is a common but often overlooked aspect of weight loss. Here’s why it happens and how you can regain hair thickness, density, and confidence with the right support.

Why Hair Loss Happens During Weight Loss

Hair growth relies on a combination of nutrients, hormonal balance, and minimal stress. When we cut calories or change our diet, the body may temporarily redirect resources toward essential functions, sometimes slowing hair growth. Here are some common factors that contribute to hair loss during weight loss:

  1. Nutrient Deficiency: Essential nutrients like protein, iron, zinc, and biotin are crucial for strong hair. Deficiencies in any of these can lead to weakened hair that’s more prone to breakage and shedding.
  2. Hormonal Shifts and Stress: Weight loss can disrupt hormonal balance, increasing cortisol levels – a stress hormone that contributes to hair loss when elevated.
  3. Rapid Weight Loss: Losing more than 2 pounds per week may cause telogen effluvium, a condition where hair shifts to the shedding phase sooner than usual.

Supporting Hair Health During and After Weight Loss

The good news is that you can still support your hair health while reaching your weight goals. Here are some helpful strategies:

  1. Prioritize Nutrient-Rich Foods
    • Protein: Since hair is largely made of protein, include it in every meal to support both hair and muscle health. Aim for about 1 gram of protein per pound of body weight daily.
    • Vitamins & Minerals: Iron, zinc, biotin, and vitamins A, C, D, and E are all essential for hair health. Leafy greens, nuts, eggs, and fish are great sources.
    • Omega-3 Fatty Acids: Omega-3s promote scalp health and can reduce inflammation. You can find these in fish, chia seeds, and flaxseeds.
  2. Manage Stress: Stress impacts the entire body, including hair. Engage in activities like meditation, exercise, or deep breathing to help lower cortisol levels. Studies show that managing stress can help support hair growth in people experiencing hair loss related to stress.
  3. Supplement Wisely: A good multivitamin or hair-supportive supplement can be a valuable addition, especially if you’re concerned about nutrient gaps. Consider one with biotin, collagen, and vitamin D, which are known to support hair health.
  4. Supportive Products: To further support hair health, consider clinically-approved products formulated to address hair loss. For example, Alan Health’s new prescription Hair Regrowth Serum.

What is Alan Health Hair Regrowth Serum?

Alan Health’s new prescription Hair Regrowth Serum combines effective, clinically proven ingredients to target the factors that lead to hair loss and promote regrowth. This formula includes:

  • Minoxidil: Known to support thicker, stronger hair growth by increasing blood flow to hair follicles, extend the duration of the anagen phase (growth phase), and can increase both length and density of hair. 
  • Ketoconazole: Helps reduce inflammation and potential hormonal contributors to hair loss.

With consistent use, these ingredients may improve scalp health, reduce shedding, and visibly enhance hair thickness and density within 2–4 months. See if you're eligible here.
