Can a shampoo stop hair loss?

Frequently asked questions about Thick Fix

What is the best shampoo for hair loss?

While there are a number of shampoos designed to help fight hair loss, few are proven to prevent hair thinning or boost hair regrowth. This is because the tried and true topical hair loss treatment, minoxidil, needs to stay on the scalp for hours without rinsing. Some shampoos may have DHT-blocking properties, especially those with ketoconazole or saw palmetto, but the research on these alternative treatments is relatively limited.

Therefore, the best shampoo for hair loss is typically one that will support your other hair loss treatments by effectively cleansing and moisturizing your hair and scalp without overly drying or damaging hair. For this reason, look for a cleanser that is sulfate-free. Sulfates strip away impurities like dirt and oil, but your hair needs some oil to stay healthy. For the record, Hims thickening shampoo is free of both sulfates and parabens.

Using a shampoo that protects hair and promotes volume can help you avoid breakage and damaged hair while also giving the appearance of thicker hair while your hair loss treatments work.

Should I use a hydrating conditioner with the thickening shampoo?

Adding a conditioner to your hair care routine can promote healthy hair growth and support your hair loss treatments. Ingredients like niacinamide, aloe, coconut oil, or argan oil are all top conditioning ingredients that support healthy hair.
Our thickening conditioner contains niacinamide to promote healthy growth and make your hair look fuller. Check out our thickening conditioner.

Does hair thickening shampoo work?

The only way to truly stop hair loss caused by male pattern baldness is to block the conversion of testosterone to DHT in the scalp. Most “hair loss shampoos” contain ingredients like ketoconazole, which have not been clinically proven to block DHT and treat hair loss like finasteride and minoxidil.

That said, healthy hair growth starts in the hair follicles. Any shampoo that helps to keep follicles healthy and clear of excess oils can be a valuable addition to your hair care routine. A shampoo with ingredients like saw palmetto or ketoconazole can support your hair loss treatment plan, but if you really want to knock out hair loss, make sure you also use a proven treatment like minoxidil or finasteride.

How does hair thickening shampoo work?

Hair thickening shampoo with saw palmetto may help target DHT, the hormone that contributes to hair loss, as well as reducing build up on the scalp. After using hair thickening shampoo, you should start to experience a thicker, fuller hair feel. However, saw palmetto is not a clinically proven or FDA approved hair loss treatment, so make sure you are also using a true hair loss treatment for maximum effect.

Will hair thickening shampoo work on fine or thin hair?

Hair thickening shampoo is designed to work well on different hair types, including thin hair, color-treated hair, and fine hair. Most men who use hair thickening shampoo are seeking a hair loss shampoo for thinning hair.

What is saw palmetto?

In nature, saw palmetto is a type of tree, and the extract of saw palmetto's fruit is used to create supplements for people with a wide range of conditions. For example, people have used saw palmetto to help with enlarged prostate, hair loss, and even urinary tract health. As a topical shampoo, saw palmetto may help to promote an environment conducive to healthy hair growth.

How else can I get fuller looking hair?

In addition to a good volume shampoo, like our hair thickening shampoo, you can do a lot to make your hair appear thicker with your hairstyle. If you have thinning or fine hair, styling your hair with too much product can result in greasy, flat hair. On the flip side, a crew cut or mop top can help disguise your thinning hair and give you a voluminous look. Learn more in our guide to haircuts and hairstyles for thinning hair.

The best hair care approach is typically to use hairstyles and thickening shampoo for thicker, fuller-looking hair in the short term, while also starting a hair loss treatment like finasteride to stop hair loss and promote hair regrowth in the long term.
