Many prescription and OTC products can help protect remaining hair and may even promote new hair growth. However, it is always important to speak with a dermatologist to find out and treat any underlying conditions that may cause hair loss.

Roman Topical Minoxidil

Type topical solution
Quantity 1-month supply
Prescription needed no
Key ingredients 5% minoxidil
GET STARTED WITH ROMAN
Ro offers prescription and OTC hair growth tablets and solutions. It offers minoxidil, an FDA-approved OTC hair regrowth product, in both topical and oral form.

Read our in-depth review of Ro here.
in-depth review of Ro
Ro states that people who use this product must only apply it to their scalp if their hair is dry. People can rub the solution onto the affected areas of the scalp twice daily, in the morning and at night.
The company ships all products for free in discreet packaging, making this a perfect option for people who want to start their hair regrowth journey with privacy.
How it works
Minoxidil works by shortening the telogen phase — the dormant phase — of the hair follicles. It also increases the length of the anagen phase, leading to increased hair growth and thickness.
This hair growth product makes a noticeable difference around 8 weeks after beginning treatment, reaching maximum effect at around 4 months.

Quantity 1 fl oz (30 mL) bottle, 2 fl oz (60 mL) bottle
Prescription needed no
Key ingredients procapil and redensyl
$21.70 AT SEPHORA
*Price may vary.
The Ordinary states that this leave-in serum is best for use just before going to sleep. The serum may help promote hair growth and thickness, particularly when people also massage their scalp.
The company recommends massaging a few drops onto clean and dry hair once per day.
How it works
One of this serum’s main ingredients is CAPIXYL, which contains acetyl tetrapeptide-3. A 2020 study found that an herbal solution including this ingredient promoted hair growth at a comparable rate as people using 3% minoxidil.

Acetyl tetrapeptide-3 can stimulate collagen production, potentially making hair appear thicker and fuller.

Castor oil is another main ingredient that may help promote hair growth. Animal studies have found that caster oil increases rabbits’ hair length, softness, and thickness. More research is necessary to determine how well it works on human hair.

$19.00 AT HIMS

OLAPLEX No.4C Clarifying Shampoo

Type shampoo
Quantity 250 mL
Key ingredient bis-aminopropyl diglycol dimaleate
$30.00 AT SEPHORA
*Price may vary.
Olaplex states that this shampoo can help remove buildup in the hair that may negatively affect hair health, such as heavy metals, minerals, chlorine, pollutants, and hair products.
The company states that this shampoo is suitable for all hair types, including colored hair. However, it also recommends people seek their hairdresser’s advice and avoid using this shampoo for the first few weeks after dying their hair.
To use this shampoo, people should lather it onto their scalp and rinse thoroughly, repeating if necessary. Olaplex recommends using this shampoo once every 1–2 weeks.
How it works
None of the ingredients in this shampoo have clinical evidence that they can increase hair growth from the scalp. However, a buildup of products on the scalp and hair lengths, such as oils, leave-in conditioners, and styling products, can weigh hair down and make hair drier and more brittle.
Clarifying shampoos, when people use them as the manufacturer recommends, can help strip away buildup — potentially reducing the amount of hair breakage. This can help people grow their hair longer without split ends or other damage.
“Olaplex No.4C worked really well for my hair!
“I have thick and coarse hair that becomes extremely frizzy in humid environments, and as luck would have it, I live in the very humid coastal England in an area with hard water! I need to use a lot of product for my hair to feel hydrated and to control the frizz, and over time my hair feels a bit gunky even straight after washing.
“I bought Olaplex No.4C to give it a whirl, as both haircare forums and my hairdresser recommended it to me. The first time I washed my hair with it, I noticed my hair looked shinier and felt so much cleaner. Volume has never been an issue for me, so I can’t verify other people’s reviews of it providing more volume to hair.
“Olaplex recommends using this shampoo once every 1–2 weeks to help remove buildup. I use it every other wash because of how much product I need to use and due to the hard water in my area, but people with finer hair and soft water may need to use it less.
“Most of my hair has dye on it, and I have noticed that the shampoo strips some of it out. However, as I am in the process of growing out the color, I don’t mind this at all.
“It is worth noting that while Olaplex says this shampoo is suitable for colored hair, it also recommends people check with their hairdresser before using the product, and avoid using the shampoo in the first few weeks after dying. I second this: there’s nothing worse than drying your hair to see your brand new color has faded!”

Head & Shoulders Itchy Scalp Care

Type shampoo
Quantity 400 mL
Key ingredient zinc pyrithione
$9.99 AT AMAZON
*Price may vary.
Head & Shoulders is a popular choice for people with an itchy scalp or dandruff.
dandruff
This shampoo contains zinc pyrithione and eucalyptus, which may help soothe itchiness. The company states this shampoo is gentle enough for daily use, even on colored or chemically treated hair.
How it works
Dandruff can cause premature hair loss, according to research.
research
Daily use of shampoo that contains zinc pyrithione — the main ingredient in Head & Shoulders — can help reduce dandruff and prevent hair loss. In fact, one of the studies the authors investigated suggested that combining daily zinc pyrithione shampoo with minoxidil could lead to an increase in new hair growth.
“I have extremely sensitive skin and generally can’t use products not designed for this issue for more than a couple of days before I get a reaction. Head and Shoulders shampoos are the only ones that do not cause a reaction, even after extended use, and they do help to calm down and manage my scalp, which can easily become dry. I have experienced hair loss due to skin conditions in the past, and this daily shampoo helped to get my scalp back into a condition where hair could grow more easily. I wouldn’t say the shampoo itself will make your hair grow — it’s more that it helps get scalp complaints that can affect the quality and health of your hair out the way.
“It has a refreshing scent, and it’s not overpowering. It includes mint, which can cool an irritated scalp, but it can sting a little if you have really irritated areas. It lathers really easily, and to make sure it’s actually getting to your scalp, it’s best to smooth it onto your hair and scalp and leave it for a minute or two before lathering. I find a little goes a long way, so the shampoo lasts for a fairly long time.”
– Lois Zoppi, Market Editor

Nioxin System 1 Cleanser Shampoo

Type shampoo
Quantity 1 L
Key ingredient peppermint oil
$42.75 AT AMAZON
*Price may vary.
This shampoo is step one of a three-step hair regime by Nioxin. The company states this shampoo is good for people with lightly thinning and natural hair.

How it works

Peppermint
An old study on animals found that 3% peppermint oil significantly increased hair amount and thickness. The authors also note that peppermint oil had faster hair growth effects than minoxidil.

Best oils for hair growth
People tend to use hair oils either just on the lengths or as part of a scalp massage.
Oiling hair lengths can help protect the hair against heat or elemental damage, reducing split ends and breakage. This can make hair look fuller and help keep it growing longer and healthier.
Oiling the scalp is typically either a leave-in treatment or a pre-shampoo treatment to try to stimulate new hair growth.

Iron deficiency can cause hair loss. Vitamin C helps the body absorb iron, making these two nutrients a good pair to consume if a person is experiencing iron-deficiency hair loss.

How we chose the best hair growth products
Medical News Today chooses hair growth products that pass our rigorous vetting criteria. Some of our considerations when choosing products include:
Effectiveness: We only include products that may help protect and nourish hair lengths and ends while encouraging hair growth. We look at clinical studies to check that the ingredients can do what the companies claim.
Type of hair loss: We include products suitable for hair breakage, light thinning, and more noticeable hair loss.
Hair type: We include products suitable for as many hair types and conditions as possible. Some products may be more suitable for coily, thick hair, whereas others may work best for fine, straight hair.
Product type: We include serums, solutions, shampoos, oils, and supplements to provide choices that fit a majority of people’s hair care routines.
Personal experience: Where possible, we include our own experiences with hair growth products.
How to shop for hair growth products
While some hair growth products may benefit all types of hair, others may be more suitable if a person knows the underlying cause of hair loss and hair thinning.
People should always contact a dermatologist to determine any underlying causes so they can choose the right product for their needs.
Other considerations may include:
Price: There are cheaper and more expensive hair regrowth products available in-store and online. Many contain similar ingredients that have some hair growth benefits.
Ingredients: The FDA does not approve most hair growth products, and some unreputable companies may make claims about ingredients that are not evidence-based. People may wish to consult with a dermatologist to determine whether the product can do what it claims.
Hair type: Some products feature specific formulas for certain hair types, such as curly or thinning hair. People can also consider how they usually style their hair and choose a product they will find convenient to use.
Hair loss causes: Many factors can cause hair loss, such as nutrient deficiency, illness, or age. Certain types of products may be more beneficial depending on what is causing hair thinning or hair loss.
How to prevent hair loss and thinning
Some types of hair loss are due to factors people cannot prevent, such as age or genetics. However, people can reduce the likelihood of premature hair loss and thinning in several ways:
Diet: Some research suggests the Mediterranean diet, as well as diets rich in protein and soy, can help to prevent hair loss.

Supplements: Not getting enough nutrients can lead to hair thinning and loss. A 2022 systematic review suggests that nutritional supplements can help treat hair loss, although people should always work with a healthcare professional to find the right supplementation.

Reduce hair styling: According to the American Academy of Dermatology Association (AAD), people should limit at-home hair coloring, perming, and the use of heat styling items such as curling tongs and hot combs. People may also wish to use a hair dryer on the lowest heat setting.

Limit smoking: A 2020 study concluded that there is a link between hair loss and cigarette smoking. The researchers also state that smoking may accelerate the hair loss process in those with androgenetic alopecia.

Reducing stress: Chronic stress can lead to hair loss. High levels of cortisol, the stress hormone, prevents the body from releasing a molecule that plays a part in hair growth.

Wash oily hair as often as it needs, even if this means daily shampooing.
Only shampoo the scalp, not the mid or end lengths of hair.
After shampooing, use a conditioner to rebuild moisture and detangle the hair.
Choose a shampoo that is suitable for a person’s hair type.
Protect the hair from harsh chemicals, such as chlorine, by wearing hats and caps.
When to see a doctor
The American Academy of Dermatology recommends consulting a doctor about possible hair loss as soon as signs of hair loss appear. This is because earlier treatment can be more effective. Early treatment can also prevent further hair loss.
