If you’re experiencing hair thinning, you’ll want to choose a shampoo that has active ingredients to help the problem at hand.

To select the best shampoos for thinning hair, we considered many factors, including:

  • Brand reputation: We chose brands you can trust and vetted each product via our brand and content integrity standards. Read more about our product selection process here.
  • User reviews: We looked for products that earned good reports from buyers.
  • Formulation and active ingredients: Wherever possible, we chose shampoos with natural ingredients that are proven to help thicken and strengthen hair.
  • Price: Finally, we did our best to include options for every budget.

Hair thinning refers to a gradual process where hair gets sparse in certain areas. It’s different from hair loss, which is defined by hair breakage from the scalp or when hair falls out from the root.

Hair loss can lead to baldness, whereas hair thinning doesn’t necessarily do so.

Genetics, medical conditions, and life circumstances (or a combination of all three) can cause hair thinning. Some of these include:

  • vitamin deficiency, particularly vitamin D, iron, B12, and folic acid
  • skin disorder or infection
  • treatment for autoimmune disease or immune system deficiencies
  • hormonal changes (including stopping birth control pills or having a baby)
  • sudden, significant weight loss
  • chronic stress

There are also lifestyle habits that can cause hair thinning. These include:

  • using harsh products on your hair, like gel and hair spray
  • overtreating your hair with relaxers and perms, chemical hair color, or heat styling tools
  • wearing tight hairstyles, like ponytails and up-dos

Beneficial shampoo ingredients for thinning hair include:

  • Histidine: This amino acid absorbs excess copper from hair, shielding it from UVA and UVB damage.
  • Phyto-caffeine: Caffeine has been found to suppress excess testosterone in the hair root. Testosterone can suppress hair growth on the head in men and women.
  • Niacin (vitamin B3): This vitamin promotes hair fullness. It also stimulates circulation and blood flow in the scalp.
  • Biotin (vitamin H): Biotin is a water-soluble vitamin that’s part of the B vitamin family. It’s important to have biotin in your diet for hair growth. Some shampoos also contain this ingredient, which may promote hair fullness and reduce breakage.
  • Essential oils: A number of essential oils have been shown to thicken hair or make it healthier and less prone to breakage. They include peppermint, lavender, lemongrass, rosemary, and thyme.
  • Minoxidil: The Food and Drug Administration (FDA) has approved this ingredient for the treatment of hair loss when used as a 2% topical solution for women and 5% for men. Some shampoos also contain minoxidil as an active ingredient.

It’s possible for some people to grow back hair after thinning or loss, but it varies from person to person and is based on different factors. For example, if the cause of your hair loss is genetic or the result of scarring, it may not be possible to regrow hair.

But many people have found success with over-the-counter hair thickening products or with prescription medications like minoxidil and finasteride.

If you’re experiencing hair loss, consider talking with your doctor or a hair loss specialist who can diagnose what’s causing your hair loss and what treatment options may be best for you.

Hair loss — meaning hair that falls out from the scalp — can occur as the result of genetics, diet, a health condition, stress, medications, and more. Addressing the underlying cause of thinning hair often reduces hair loss over time.

Once you’ve addressed the underlying cause, a shampoo with the following ingredients may be helpful:

  • histidine
  • peppermint
  • phyto-caffeine

You may also notice that your hair appears to break off more easily and seems to be thinner and weaker than it was in the past.

Hair breakage may be the result of styling habits over time, like using heat to style your hair. Using harsh shampoos, overwashing, and not conditioning your hair can also cause it to break and thin. Modifying these habits can help restore your hair.

Shampoo ingredients that may strengthen hair and help it appear fuller include:

  • ginseng
  • biotin
  • collagen
  • aloe vera

Since diet can affect hair growth, eating enough iron and protein may also be beneficial.

There are several vitamins and nutrients that are beneficial for hair growth. Too much of others, like vitamins A and E, may actually worsen hair loss.

Always consult a healthcare professional before adding supplements to your diet.

There are many other treatments for thinning hair, in addition to shampoo.

Scalp massage, either with your fingers or a handheld device, can stimulate hair follicles and encourage growth. Laser therapy, used in office by a dermatologist or with an at-home device, can help regrow hair as well. But these treatments don’t work for everyone, and they can take months to see results.

Platelet rich plasma injections, which help create a healthier environment for hair growth, are also an option.

Another way to address thinning hair is by making sure your body is sufficient in vitamins, especially iron, vitamin D, folic acid, andzinc.

While vitamins can’t reverse hair loss, taking adaily multivitamin that includes iron, vitamin D, folic acid, and zinc can help hair grow thick and strong. (A blood test can determine if you’re low in nutrients.)

Supplements like omega-3andomega-6fatty acids and biotin can also have a positive effect on your scalp and hair health.

Thinning hair and hair loss can be caused by a wide range of conditions, including stress, aging, genetics, and illness. Styling habits can also cause hair to become thin and breakable.

There are a number of active ingredients that can help reduce hair thinning and also promote the look of fullness.

It’s important to understand and address the underlying cause of your thinning hair.
