8 Common Reasons Your Hair Might Be Thinning

8 Common Reasons Your Hair Might Be Thinning

Noticing more hair in your brush or shower drain? You’re not alone. Shedding is a common experience at many stages of life. Here, we break down eight of the most frequent causes — and what they could mean for your hair and scalp health.

 

 

1. Genetics

If hair thinning runs in your family, chances are your strands might start to follow suit. Hereditary hair loss often appears gradually — maybe a little less volume at the crown, or a hairline that subtly shifts over time. While you can’t rewrite your DNA, you can stay ahead of it. A consistent, scalp-focused routine can help maintain fullness and keep your hair looking its best, longer.

2. Medication

Some medications can quietly affect your hair, with shedding as a common side effect. Antidepressants, hormonal treatments, and blood thinners are frequent culprits, and some women notice changes after stopping birth control. If the timing aligns, speak with your doctor about options or ways to support your hair while staying on track with your health.

 

 

3. Hormonal Changes

Hormonal shifts during pregnancy, postpartum, or menopause can lead to noticeable hair shedding — and it’s more common than you think. Our founder went through it herself and developed the Density Kit to help others going through the same experience. This three-step routine gently supports scalp health and encourages regrowth, with many noticing visible improvements in just a few weeks.

 

4. Illness or Recovery

Hair loss can be your body’s way of reacting to illness or a change in your immune system. Many people noticed hair shedding after recovering from COVID-19. Autoimmune conditions like alopecia areata can also cause patchy hair loss. If your hair loss is sudden or extreme, it’s best to consult a healthcare professional.

 

5. Stress

Stress affects more than just your mood — it can actually pause your hair’s natural growth cycle. If you’ve been going through a rough patch, your hair might be feeling it, too. One of the easiest ways to start supporting your scalp is by switching to our Density Shampoo. It’s a gentle, nourishing formula designed to soothe the scalp and strengthen roots — a simple first step in easing stress-related hair loss.

 

 

6. Poor Nutrition

Healthy hair starts from within. When your diet lacks essentials like protein, iron, or key vitamins, it can show up in the form of dullness, breakage, or excessive shedding. Focus on nutrient-rich whole foods, and consider supplements like biotin, zinc, and B vitamins to help support stronger, fuller strands from the inside out.

 

7. Aging

With time, it’s natural for hair to lose some of its density. As follicle activity gradually slows, strands may grow finer and shedding can become more noticeable. While aging is part of the journey, targeted scalp treatments and consistent care can help maintain volume and keep your hair looking healthy and full at every stage.

 

8. Hair Damage

Coloring, bleaching, heat styling — we’ve all been there. While these habits don’t directly cause hair loss, they can leave your hair dry, brittle, and more likely to break. To help repair and protect, try our Density Conditioner. It’s infused with shea butter and hydrolyzed quinoa to deeply nourish damaged hair and provide lightweight heat protection — the perfect way to give your strands the break they deserve.
