The 13 Best Hair Growth Serums

Best Overall: Wild Growth Hair Oil

Wild Growth
With nearly 30,000 reviews on Amazon, this hair growth serum is by far the most popular! Its all-natural formula is packed with various oils and extracts that are seriously great for hair and scalp health, which can in turn promote faster hair growth. These ingredients include coconut, jojoba, olive oil, cocoa butter, rosehip rice bran and tons of other nutrients too extensive to list out in their entirety.


It does have a thicker consistency, which can make your hair feel greasy, but it’s not designed for everyday use. If your hair is on the greasier side, you can still use this oil as a nighttime treatment and wash it out the next morning without issues. Shoppers say that when used correctly, their hair has ‘seen tremendous growth’ in a matter of weeks!

  • All-natural formula
  • Amazing reviews

Best Non-Greasy Formula: Briogeo Destined For Density

Briogeo Destined For Density MegaStrength + Caffeine + Biotin Peptide Density Serum | Increases Hair Thickness and Density, Fast-Absorbing & Non-Greasy | Vegan, Phalate & Paraben-Free | 1.5 Ounces
If you have an oilier scalp but still want to use a serum to promote hair health, this lighter formula that’s non-greasy and fast absorbing may be the right option! It’s designed to help strengthen hair and help anyone who struggles with hair density and excessive hair shedding.


The formula includes biotin, copper peptides and caffeine to help stimulate the hair follicle on areas of the scalp which have sparser growth to help fill in those gaps. You can also use it throughout the scalp as needed, but the smaller size of the bottle suggests that it’s more of a spot treatment. For the best possible results, use it twice daily, and over the course of a few months, your hair density may significantly improve. Some shoppers say it only took them six weeks so see ‘significant growth,’ which is impressively fast!

Finding the Best Hair Growth Serums: A Buyer’s Guide

Hair is a very sensitive subject for many, especially those who deal with thinning and excessive shedding. Feeling like you’re losing your hair at rapid speed is discouraging, which is why you may be on the hunt for a great hair growth serum to help bring your confidence back. The only problem which may come up while shopping for a treatment is not knowing how to narrow down your options, which is why this guide was created.

Now that you know the range of different hair growth serums to choose from and what makes each of them special, it’s important to take a look at your own hair and see which one of these will best fit with what you’re looking to accomplish. If you’re still struggling with making a final decision, there’s additional info below which may be helpful in steering you in the right direction!

What to Consider When Choosing the Best Hair Growth Serums

When choosing the best hair growth serums for your needs, it may help to consider the following features:


Any hair care product will inevitably vary in price, but this is especially true for hair growth serums. Because they take time to show results, you’ll likely need to wind up buying the product more than once. There are bottles which can cost less than $10, and others that are upwards of $100 — so considering the cost needs to be a top priority.


Most hair growth serums will come in bottles which contain a one-month supply, but some will have more or less depending on the brand. When you compare the cost of the serum with the size of the bottle, you’ll get a better understanding if it’s worth buying. The budget you’re working with and the amount of product you’re getting definitely go in hand in hand when making your decision.

Hair Type

Taking your hair type into consideration with hair growth serums mainly boils down to figuring out if your hair (and scalp) is oily or more dry. Many serums have oil-based formulas which works for dry scalps, but if you’re concerned that will make your hair look greasier, keep an eye out for lightweight options.

Use Frequency

Some hair growth serums are designed to be used a few times per week for the best results, and others recommend daily or even twice-daily use. Check out and see how frequently you’ll need to use the serum you’re thinking about buying and figure out if the routine can easily fit into your daily life. No one needs extra steps!

User Reviews

While reviews don’t always define how effective a hair growth serum can be for you personally, they’re certainly a good indicator of how successful a product is overall. Reading what shoppers have to say about their own experiences can also help you figure out if the serum you’re looking into aligns with your hair type and the results you seek to achieve.

What are the Different Types of Hair Growth Serums?

The following are the most common types of hair growth serums.

Minoxidil Serums

When researching hair growth serums and treatments, minoxidil is one of the ingredients you’re bound to come across most frequently. Minoxidil helps generate new hair growth, which is especially effective for hair loss due to aging or genetics, but it can also come with some side-effects which are important to review before going with this type of serum.

Peptide Serums

Serums which contain peptides can help foster a healthier scalp to promote new hair growth, plus strengthen and thicken existing strands. Using this type of hair growth serum may be a better option for anyone who has a more sensitive scalp and is looking for a gentler treatment that’s said to be equally as effective.

Plant-Based Serums

There are plenty of natural remedies which are implemented in hair growth serums to seriously improve hair thickness, overall health and length. If you want to take a vegan approach with your hair growth serum, there are tons of formulas to choose from, and they may even be a better fit for your specific lifestyle.

What are the Different Uses for Hair Growth Serums?

The following are the reasons why people use hair growth serums.

Hair Lengthening

By nature, hair growth serums can help your hair grow longer faster, because they’re made to help nourish your scalp and hair follicles. If you haven’t prioritized creating a healthy environment on your scalp and have noticed your hair hasn’t been growing as fast as you may want it to, serums can help you get to your desired length.

Hair Thickening

Tons of shoppers turn to hair growth serums because their hair has lost its thickness over time. This is another amazing benefit — these treatments can give your strands a fuller look, which may also make your hair stronger in the process.

Hair Regrowth

Hair loss is something that’s difficult to deal with, and it can occur for a number of different reasons. What many hair growth serums are designed to do is help re-stimulate growth in areas where strands are sparse and fill in these gaps. This may give your locks a fuller and healthier look.

Additional Questions and Tips to Choose the Best Hair Growth Serums

When narrowing down your list, ask yourself these questions and consider these buying tips to help ensure you pick the best hair growth serums for your needs. 

Is this serum color-safe?

If you get your hair dyed, it’s imperative to make sure the hair growth serum you go with is color-safe. Chemical treatments damage strands, which may be a reason why you’re seeking out a hair growth treatment in the first place. To help you prevent even further distress on your hair, be sure to check if the serum you go with is gentle enough for your unique color-treated hair.

Who is this serum designed for?

Tons of hair growth serums are designed for both men and women, but if you want one specifically designed for whomever you’re shopping for, you can take that into consideration. While this may not be a major deciding factor, it’s something to ponder.

Can I afford the upkeep with this serum?

Taking a look at the specific instructions when deciding which hair growth serum to go with is incredibly important for two reasons. You should consider if the specific formula can fit into your day-to-day life, but also if you can also afford to stick with the serum you’re choosing. It typically takes at least three months to see the full effects of any hair growth serum, and most are packaged into one-month supply bottles. So, considering how often you’ll need to make another purchase is certainly top of mind for many of Us during this process.
