Want thicker hair? Explore expert reviews of the top-rated hair growth sprays that actually work. See which spray suits your hair type.

If you’ve been scrolling on TikTok or Instagram recently

it’s likely that you’ve seen someone proclaiming about a magical spray that helps you achieve thick, full hair. Hair growth sprays are the shiniest new beauty trend that is going viral on social media—but do they work? With the uncertainty of different products and lots of options, it can be hard to determine what’s hype and what’s real.

In this expert-reviewed guide, we’ll explain the best hair growth sprays, their ingredients, who they work for, and what dermatologists and trichologists (hair experts) actually think. Whether you are experiencing postpartum shedding, stress-related thinning, or just want the “thick and healthy hair flip” that you saw on TikTok, this is for you!

Why Is Everyone Talking About Hair Growth Sprays Right Now?

Social media is an effective platform for beauty transformations, and hair-based content is rising. From before-and-after shots to video tutorials of stress-releasing scalp massages, creators are showing that they achieve results through the use of hair growth sprays. Tools like oils or serums can provide a heavy, messy feel, but unlike these products, sprays are lighter and easier to use, making them perfect in the rush of busy lifestyles or when on the go.

There is a movement taking place that aligns with a bigger push toward scalp health as its own category of skincare. Just as people are proactively using serums and actives for the face, they are now beginning to understand the scalp deserves some love, too. Hair growth sprays are full of ingredients to not only stimulate hair follicles but also promote scalp health overall.

How Do Hair Growth Sprays Work?

Supplements for hair growth focus on the active phase in the hair growth cycle, called the anagen phase. Sprays can encourage the anagen phase by having ingredients which:

  • Encourage blood circulation to the scalp
  • Enrich the follicles with vitamins and proteins
  • Regulate inflammation
  • Block DHT (a hormone tied to hair loss)
  • Contribute to hydration / regulate flaking

And while no spray will grow back a bald head overnight, over time, daily use of a hair growth spray can support sustained, stronger hair growth – even when used in association with a regimen of other healthy living habits.

Key Ingredients to Look for in Hair Growth Sprays

Experts all agree that the brand is not important; what is in the bottle is far more important. Based upon an analysis of hair growth sprays, the most effective ones tend to have one or more of:

Ingredient   Purpose

Minoxidil (FDA approved)      restarts the hair growth process and reawakens   

dormant follicles

Biotin supports the health of each hair strand and supports growth

Caffeine    

improves circulation and stimulates hair roots

  • Peppermint Oil    increases circulation and stimulates a cooling sensation
  • Saw Palmetto      blocks DHT, thereby preventing hair from thinning
  • Niacinamide         caland and support scalp barrier
  • Ginseng                energizes the follicles and amplifies density

Rosemary Extract is a stimulant for natural hair growth and offers       anti-inflammatory benefits

You should always read the label and do a patch test before using the product.

Be Consistent: Use the spray as advised- ideally daily.  Growth is a slow process. Often, one will see results in 2-4 months.

Massage It In:  Scalp massage initiates circulation and thus accomplishes active ingredient absorption- use your fingers or a scalp massager.

Clean Scalp = Better Absorption: Make sure you are applying the spray to a clean, dry (or lightly damp) scalp.

Eat Well:  Protein, iron, and omega-3 fatty acids all help with hair health.

Be Patient:  Growth takes time. Don’t jump from spray to spray too prematurely.

What Do Dermatologists Say About Hair Growth Sprays?

Most dermatologists agree that topical treatments like sprays work, especially when combined with other routes of treatment (i.e., microneedling, oral supplements, laser therapy, etc.). However, not every cause of hair loss will respond to sprays. If you are experiencing sudden or extreme hair loss, consult with a physician.

Consider Trying Hair Growth Spray.

If you are looking for an easy, effective way to increase thickness and reduce shedding, hair growth spray might be a new favorite in your routine. With a plant-based serum like Vegamour, an affordable option like The Ordinary, or a hormonal support formula like Nutrafol, there is something for every scalp and budget.
