“Hims thickening shampoo is the best shampoo I've tried for my very fine thinning hair. The DHT blockers seem to be keeping a lot of my hair on my head. The shampoo is also moisturizing. My hair feels and looks great! I definitely recommend.”

Can a shampoo stop hair loss?

More of a supporting role

This thickening shampoo is packed with saw palmetto (which can block some DHT) but when it comes to male pattern baldness, you might need a prescription strength treatment (such as finasteride & minoxidil) to help stop hair loss and regrow hair.

A great addition to the team

Thick Fix was formulated with dermatologists using the best ingredients to get thicker, fuller looking hair. It also strengthens new hair coming in so it’s a great sidekick to any hair loss treatment.

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.

Read this patient information before you start using this medication and each time you get a refill. There may be new information. This information does not take the place of talking with your healthcare provider about your medical condition or treatment.
Topical finasteride + minoxidil spray is a prescription medication used for the treatment of male pattern hair loss (androgenetic alopecia). It is a treatment alternative to oral finasteride that has been shown in research studies to be safe and effective. Unlike oral finasteride, topical finasteride + minoxidil spray is a compounded product and has not been approved by the FDA. It is only available if prescribed after an online consultation with a medical provider through the Hims platform. The use of topical finasteride to treat hair loss has not been as comprehensively studied as oral finasteride. While research has shown that serum DHT levels decrease while using topical finasteride, the systemic side effects (e.g., sexual dysfunction) typically associated with oral finasteride were not reported in the studies of topical finasteride.
Do not use other topical minoxidil products while you are using the Topical finasteride 0.3% + minoxidil 6% spray.
Do not allow individuals who are pregnant or breastfeeding, individuals who have the potential to become pregnant, or children handle this medication. Do not allow any of these individuals to come into contact with the treatment site (your scalp) after the medication has been applied. If they do, they should immediately clean the site of contact on their skin with soap and water.

  • are currently taking other medications in the same class as finasteride (5-alpha reductase inhibitors: dutasteride, Avodart®, Jalyn®)

Important Safety Information

Finasteride is for use by MEN ONLY and should NOT be used by women or children.
Read this patient information before you start taking Finasteride and each time you get a refill. There may be new information. This information does not take the place of talking with your healthcare provider about your medical condition or treatment.
What is Finasteride?
Finasteride is a prescription medicine used for the treatment of male pattern hair loss (androgenetic alopecia).
It is not known if Finasteride works for a receding hairline on either side of and above your forehead (temporal area).
Finasteride is not for use by women and children, and should not be handled by women and children.
Who should not take Finasteride?
Do not take Finasteride if you:
  • are pregnant or may become pregnant. Finasteride may harm your unborn baby.
    • Finasteride tablets are coated and will prevent contact with the medicine during handling, as long as the tablets are not broken or crushed. Females who are pregnant or who may become pregnant should not come in contact with broken or crushed Finasteride tablets.
    • If a pregnant woman comes in contact with crushed or broken Finasteride tablets, wash the contact area right away with soap and water. If a woman who is pregnant comes into contact with the active ingredient in Finasteride, a healthcare provider should be consulted. If a woman who is pregnant with a male baby swallows or comes in contact with the medicine in Finasteride, the male baby may be born with sex organs that are not normal.
  • are allergic to any of the ingredients in Finasteride.
What should I tell my healthcare provider before taking Finasteride? Before taking Finasteride, tell your healthcare provider if you:
  • have any other medical conditions, including problems with your prostate or liver.
Tell your healthcare provider about all the medicines you take, including prescription and nonprescription medicines, vitamins, and herbal supplements.
Know the medications you take. Keep a list of them to show your healthcare provider and pharmacist when you get a new medication.
How should I take Finasteride?
  • Take Finasteride exactly as your healthcare provider tells you to take it.
  • You may take Finasteride with or without food.
  • If you forget to take Finasteride, do not take an extra tablet. Just take the next tablet as usual.
Finasteride will not work faster or better if you take it more than once a day.
What are the common side effects of this medication?
Common side effects include rash, breast tenderness or enlargement (reported in less than 1% of patients) which typically resolve after the medication is stopped, and sexual dysfunction (in clinical trials, 1.2%-1.4% of patients taking Finasteride experienced medication-related sexual dysfunction side effects including decreased libido, erectile dysfunction or a decrease in the volume of ejaculation vs. 1% of those taking placebo):
  • Decreased libido 1.8%
  • Erectile dysfunction 1.3%
  • Decreased volume of ejaculate 1.2%
Several studies have documented the majority of these side effects are reversible. However, 1.4% of the patients who experience side effects may continue to have symptoms following discontinuation of Finasteride. Of particular note there has been an association of the sexual dysfunction symptoms and the use of NSAIDS (Motrin, Advil, Aleve type medications.) For this reason Finasteride should be stopped for the period of time when you take NSAIDS.
Does Finasteride cause depression?
A literature review shows there may be evidence of increased depressive symptoms in individuals younger than age 45 while using Finasteride for hair loss. Patients with new or worsening depression should stop Finasteride use and follow up with their health care provider or a mental health therapist. Source: MedPageToday.org
Does Finasteride cause prostate cancer or prostate enlargement (BPH)?
There have been reports of a slight increased risk (1.8% with 5mg Finasteride dosage versus 1.0% placebo) of high grade prostate cancer for men over age 55 years old. These reports are from men taking a higher dosage of Finasteride (5mg) than the dosage we prescribe for hair loss (1mg). There have been conflicting studies on the increased risk in the number of high grade prostate cancers; however, several recent studies have shown no increase in the number of deaths (with a recent study showing fewer deaths) in patients who use Finasteride at the 1mg dosage. Finasteride can be useful in the treatment of BPH and urinary retention because it can have an antiandrogenic effect (testosterone blocking) at a 5mg dosage. For hair loss, patients are given a 1mg dosage, which should not produce any antiandrogenic effect.
Does Finasteride change blood Prostate Specific Antigen (PSA) levels?
Finasteride can affect a blood test called PSA (Prostate-Specific Antigen) for the screening of prostate cancer. If you have a PSA test done you should tell your healthcare provider that you are taking Finasteride because Finasteride decreases PSA.
The following have been reported as less common side effects with Finasteride use:
  • Allergic reactions including: rash, itching, hives and swelling of the lips, tongue, throat, and face
  • Testicular pain
  • Male infertility and/or poor quality of semen
  • In rare cases, male breast cancer
Tell your healthcare provider if you have any side effect that bothers you or that does not go away.
These are not all the possible side effects of Finasteride. For more information, ask your healthcare provider or pharmacist. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088
The following have been reported in general use with Finasteride:
  • breast tenderness and enlargement. Tell your healthcare provider about any changes in your breasts such as lumps, pain or nipple discharge.
  • decrease in sex drive that continued after stopping the medication.
  • allergic reactions including rash, itching, hives and swelling of the lips, tongue, throat, and face.
  • problems with ejaculation that continued after stopping medication.
  • testicular pain.
  • difficulty in achieving an erection that continued after stopping the medication.
  • male infertility and/or poor quality of semen.
  • in rare cases, male breast cancer.
Depression: A literature review shows there may be evidence of increased depressive symptoms in users younger than age 45 while using finasteride for hair loss. Patients with new or worsening depression should stop finasteride use and follow up with their health care provider or a mental health therapist. Source: MedPageToday.org
