Our adult life is full of challenges that can interrupt our hair’s natural growth cycle—stress, nutritional deficiencies, menopause, and postpartum hormonal changes, to name a few. These factors can lead to noticeable hair thinning and loss, which can leave us feeling frustrated and self-conscious.
Maybe you’ve noticed more strands in the shower drain, a thinner ponytail, or even struggled to cover balding spots. Whatever the case, hair loss can take a toll on your confidence—some of us know this all too well.
The good news is that hair loss is often not permanent when addressed with the right solution. Hair growth shampoos offer a simple, effective way to help because they fit seamlessly into your current routine—no extra steps required. These specially formulated shampoos nourish the scalp, strengthen hair follicles, and promote new growth, giving you thicker, healthier hair over time.
To make your search easier, we’ve done the hard work for you. After extensive research, testing, and reviews of the best hair growth shampoos available, we’re here to guide you toward finding the perfect match. Our mission? To give you the knowledge and confidence to choose a product that restores your hair’s fullness, softness, and shine.
Before we dive into our top picks, it’s important to know what to look for when shopping for a hair growth shampoo. To help, we consulted Dr. Ashley Magovern, a dermatologist based in Manhattan Beach, California, for expert tips on what makes a high-quality hair growth shampoo. Let’s explore the five key factors she recommends keeping in mind.
1. Biotin
Biotin, or Vitamin B7, is a vital nutrient that plays a key role in hair health. It enhances the production of keratin, a structural protein that strengthens hair strands, reducing breakage and making hair appear thicker and longer over time.
2. pH Balanced
Maintaining the right pH level in a shampoo is crucial for scalp and hair health. A balanced pH (typically between 4.5 and 5.5) protects the scalp’s natural barrier, preventing excess dryness and irritation. A pH-balanced formula can also reduce cuticle swelling, minimizing frizz and breakage and supporting an environment conducive to hair growth.
3. Clinical Testing
When you invest in a new product, you want to be confident that it will work. Clinical testing ensures the shampoo’s safety, effectiveness, and quality. Products tested in clinical trials demonstrate measurable improvements without irritating side-effects.
4. Sulfate- and Paraben-Free
Sulfates and parabens are generally not great for hair, especially color-treated hair. Avoiding these harsh chemicals is important for gentle and effective hair care. Sulfates can strip hair of natural oils (and hair dye) and can cause dryness. Parabens may irritate sensitive scalp skin.
Now that you know what to look for when shopping for the top hair growth shampoos on the market…let’s dive into our top picks. These shampoos not only meet the criteria for effective, gentle, and nourishing hair care but also demonstrate measurable improvements without irritating side effects. Here are the standouts that deserve a spot in your routine.

Nutrafol Shampoo is a strong contender when it comes to healthier, fuller hair. Plus, the refreshing scent enhances the experience, making it a favorite for many.
While highly effective, the shampoo’s high price and challenging bottle design—hard plastic with a non-flip cap—are common critiques. Some users also report issues with color-treated hair or occasional dryness.
Despite these drawbacks, Nutrafol Shampoo is our second choice because it works better in combination with Nutrafol supplement. Also, there’s room for improvement in packaging and affordability to make it even better.
PROS:
- Pleasant fragrance
- Hair feels softer
- Physician-formulated
CONS:
- Bottle design; hard to get shampoo out
- Price compared to results
- Can have drying effects
- Some say its not truly color-safe
Regular Price: $48.00
Customers often praise its pleasant, long-lasting fragrance, which adds a luxurious touch to their hair care routine. Many users also report that it enhances their hair care experience, leaving their hair feeling softer and healthier.
However, the high price point and small bottle size are common complaints, with many feeling the results don’t justify the cost. Additionally, some customers with oily hair or sensitive scalps note that the shampoo makes their hair greasy more quickly than expected.
While this shampoo shows potential for improving hair health for certain users, addressing these concerns could make it a more universally appealing choice
PROS:
- Clinically tested
- Has biotin
- Sulfate-free
CONS:
- Leaves an oily residue
- Some complaints about scalp irritation
