The best shampoos for thinning hair are specifically formulated to address the unique needs of individuals experiencing hair loss or thinning. They often contain ingredients like biotin, caffeine, and keratin to promote hair strength and thickness while also providing a gentle cleansing experience. When selecting a shampoo for thinning hair, consider products that are free from harsh chemicals and sulfates to help maintain scalp health and encourage the growth of fuller, healthier locks. Our Editor-in-Chief even chimed in with his own recommendation that’s helped him feel better about those thinning locks on his head, too.

Why does hair loss happen? Outside of genetics, life phases can be the cause. Menopause can result in a number of unpleasant symptoms, such as hot flashes or insomnia. However, one side-effect that many overlook is thinning hair and hair loss among middle-aged women. Estimates show that about 40 percent of women over the age of 60 will develop female pattern hair loss or androgenetic alopecia. 

Something you can control though is how much fat you eat and the number on the scale. A recent study revealed that too much fat in your diet can also be bad for your hair. Researchers from Tokyo Medical and Dental University discovered that a high-fat diet accelerates hair thinning and hair loss as we age. Obesity also contributes to less luscious locks. Here’s why: In studies using mice, obesity introduced certain inflammatory signals to the body, blocking hair follicle regeneration and eventually leading to the loss of the follicles.

What causes hair thinning?

The sight of your once-luscious locks leaving a trail on your brush can be unsettling. But before you jump headfirst into a sea of miracle product promises, let’s dive deeper into the root causes of this common concern. By understanding why your hair might be thinning, you can make informed choices about the best shampoo and treatment options for your unique situation.

Hair loss can be triggered by a multitude of factors, both internal and external. Here are some of the most common culprits:

  • Genetics: Androgenetic alopecia, or hereditary hair loss, is often influenced by genes you inherit from your parents. It typically manifests as a receding hairline in men and diffuse thinning on the scalp in women.
  • Hormonal Changes: Like we previously mentioned, fluctuations in hormone levels, like those experienced during pregnancy, menopause, or thyroid disorders, can temporarily disrupt the hair growth cycle and lead to thinning.
  • Stress: Chronic stress can send your body into overdrive, impacting hair growth and potentially leading to temporary or even permanent hair loss.
  • Nutritional Deficiencies: A lack of essential nutrients like iron, protein, vitamin D, and biotin can impair hair follicle function and contribute to thinning.
  • Medical Conditions: Certain medical conditions, like autoimmune diseases or scalp infections, can damage hair follicles and cause hair loss.
  • Medications: Some medications, such as chemotherapy drugs or blood pressure medications, can have hair loss as a side effect.
  • Hair Care Practices: Harsh hair styling techniques, excessive heat styling, or tight hairstyles can damage hair over time and lead to breakage and thinning.

The right ingredients for hair loss:

Once you have a better understanding of the potential cause of your hair thinning, you can choose a shampoo that’s specifically formulated to address your needs. Here are some general tips:

  • For Hereditary Hair Loss: Look for shampoos with ingredients like minoxidil or caffeine, which can stimulate hair follicles and promote growth.
  • For Hormonal Changes: Opt for gentle, sulfate-free shampoos that won’t irritate the scalp and may help to balance hormones.
  • For Stress-Related Hair Loss: Choose shampoos with calming ingredients like lavender or chamomile, which can promote relaxation and potentially reduce stress-induced hair loss.
  • For Nutritional Deficiencies: Look for shampoos rich in biotin, zinc, and other essential nutrients that nourish hair follicles from the outside in.
  • For Medical Conditions: Consult your doctor for recommendations on the best hair care approach for your specific condition.

Remember: There’s no one-size-fits-all best shampoo for thinning hair. The key is to identify the underlying cause of your hair loss and choose a product that’s targeted towards your specific needs. By combining the right shampoo with healthy hair care practices and potentially addressing any underlying medical conditions, you can give your hair the best chance of thriving.

Bonus Tip: Consider consulting a trichologist, a specialist in hair and scalp health, for personalized advice on managing your hair thinning.

Sometimes hair loss is normal, like after pregnancy or with age. But if you have what you’d consider an excessive amount of lost strands, consult with a medical professional to diagnose the root of the problem. If you’re just wanting to give your hair a boost, reach for the best shampoo for thinning hair. We combed through 12 expert reviews to come away with the top five products for you to try.

Cosmopolitan says, “This gentle shampoo earns [a] spot on this list due to its ability to remove build-up that tends to clog hair follicles and create a less-than-ideal environment for hair growth.

Editor’s Choice: Hawthorne Thickening Shampoo

“Seeing my hair become significantly thinner in recent years has been a tough slap in the face when it comes to aging. Yep, it’s just one more realization that I’m over the hill. I’ve tried different thinning shampoos in that time, including some of the very expensive bottles. Sometime last year I gave Hawthorne a shot, and it can’t be pure coincidence that my hair feels and looks thicker than it’s been in quite some time,” says StudyFinds Editor-In-Chief Steve Fink.

“Besides the pleasant woodsy scent that isn’t too overwhelming (I hate any shampoo that I can smell on my pillow or just from moving around at any point), I don’t need to use too much to get a solid lather, even for having longer hair. I have no plans to give anything else a try for now. At about 12 bucks a bottle, Hawthorne is getting the job done, and well.”

    Look for the best drugstore brand on Google. The prices are usually a little better if money is tight.

  2. Southpaw says:

    I like Pura d’or. Been using it for a while now, and I’ve noticed a big difference. The amount of hair I now lose in the shower is minimal. That includes washing my hair every 3rd day. I use dry shampoo in between if I have to.

    It’s pricey, but it works, and the bottle is big so it will last a long time. That’s another factor to weigh in when buying a pricey product.

    Unfortunately red meat is not a good idea if you suffer from cholesterol and / or heart disease.
    Not to mention IBS and other stomach disorders like coeliac

  4. DEBBIE says:

    Ooooh,..In the 90s I was breaking out under my chin and ears. I didn’t believe the Beverly Hills plastic surgeon (scar to fix, that’s all) when he told me I was breaking out due to the fruity and herb shampoos and conditioners that were popular then, but I stopped using them and he was right. All the zits (and scars–I had to bleach the skin around the white scars.Alot of time and work and prescriptions so strong they are now away. Heed his advice!
