A reviewer says: "I have recommended this to so many people because I noticed how my hair grew so fast and usually it doesn't. It really strengthens the strands and gives you healthy hair."

"Shampoos, or cleansing detergents, do not technically aid in hair growth," says trichologist Bridgette Hill. "They're designed to remove surface dirt and debris. Hair growth is polygenic, meaning there are many genes involved that result in hair loss, yet could be triggered by something as simple as an allergic reaction to products."

She continues, "Often, consumers are led to believe the shampoo is the key to correcting hair concerns, when in fact using the wrong shampoo may be a direct causal factor contributing to hair loss and hair fiber damage."

That said, the best hair growth shampoos can be a great addition to your routine, since they "cleanse the scalp and create a healthy environment for hair growth," adds Dr. Amin.

"There are active ingredients and botanicals that can help maintain a balanced microbiome and encourage blood flow, while also superficially binding to the scalp and base of the hair fiber to aid in regulating disrupted hair cycles and nourishing the hair fibers," says Dr. Amin. "Essential oils like peppermint oil aid in stimulating blood flow, and anti-inflammatory oils such as orange, rosemary, and lavender can soothe and purify the scalp."

When looking for the best formulas, Dr. Amin also recommends options made with vitamins A, D, E, prebiotics, and DHT-blocking saw palmetto.

"Hair growth is predisposed by our individual genetics, and follicular hair growth function," explains Hill. "So no matter how consistent we are with our scalp and hair routines, our hair will only grow to a certain genetically predisposed length and rate. Introducing proper scalp care into your haircare routine will impact the rate of hair growth and health of the hair fiber."

"Results vary based not only on the changes made in a shampoo and cleansing routine, but the changes in overall scalp care and haircare routines," she adds. "With active topical ingredients applied to the scalp, it may take 30 to 90 days for the skin on the scalp to benefit from the actives. Hair fibers and the hair follicle are nonessential tissues, therefore, one of the last tissues to receive necessary minerals and nutrients. Any long-term mineral or nutritional deficiencies may lead to brittle, weak hair fibers that shed or appear as if the hair does not grow."

"Implementing a proper shampooing regimen is a game changer for maintaining a healthy scalp and hair length," says Hill. "The when and how we shampoo is equally as important as what we should use to shampoo. Certain scalp and hair types require more frequent cleansing than others. I also encourage everyone to reevaluate their shampoo routine based on their lifestyle. For example, consider the days you work out, and create heatless hair styling tricks [when possible]."

"Remember that our hair is a delicate fabric, and shampooing should not be viewed purely as a hygienic act," she adds. "Yes, it is true that our scalp and hair fibers only thrive in a clean nurtured environment, but cleansing and nurturing the scalp and hair can be achieved in other ways than detergent-based shampoo alone. Shampoos have a much-needed place in the scalp and hair cleansing category, but we must be mindful that the goal is to create balance so that the scalp's natural cleansing functions are allowed to remain harmonious."
