Best Hair Growth Products for 2022

Growing your hair out can be a lengthy process — pun intended. But if you’re looking for some help with hair growth products, there are special ones on the market that can take the frustration out of the process (and maybe even speed things up). Whether you’re searching for a hair growth serum, hair growth supplement or other treatment, you’ll find tons of hair growth products claiming to target issues like hair thinning and hair loss or to boost overall hair health.

Most of them are reasonably priced, but not all hair growth products are created equal. I spoke with dermatologists to find out what to skip and what’s actually worth trying. 

Sometimes problems like hair loss or thinning are related to underlying health issues. That’s why if you’re experiencing problems with hair loss, you may want to consult a doctor first.

There are many different types of hair loss, according to San Francisco-based board-certified dermatologist Dr. Caren Campbell and identifying your type is the first step to getting proper hair regrowth treatment. “There are various forms of hair loss, some temporary, some slowly progressive and some permanent and scarring. If you know what type of hair loss you are experiencing you can best treat it,” says Campbell.

What causes hair loss or thinning hair?

Hair loss and thinning hair are complex — which is why you want to have a medical professional evaluate you to help figure out what the cause could be, or help you figure out appropriate treatment.

According to Campbell, some forms of hair loss are related to autoimmune disease, which you want to rule out as well. Other potential culprits are medication-induced hair loss, anemia or thyroid problems. “Bottom line — there is not one catch-all treatment for all forms of hair loss. You need to first know what form of hair loss you have, what the cause might be and then treat it with that information,” says Campbell. 

“Depending on the type of hair loss you’re experiencing, [doctors] may be able to diagnose it by just your history and scalp/hair exam. However, they may recommend obtaining lab studies and/or a biopsy for additional information. Once you’ve obtained a diagnosis, you can narrow your treatment options to ingredients designed to specifically help your type of hair loss,” says Dr.
