Think trims boost growth? Or that expensive shampoos are the secret to long, luscious hair? We hate to break it to you—but most of what you’ve heard about hair growth is totally wrong. With input from dermatologists and trichologists, we’re separating fact from fiction to help you build a hair routine that actually works.

Myth #1: Does Trimming Make Hair Grow Faster?

The Myth: Frequent trims are said to boost hair growth.

The Reality: “Trimming maintains your hair’s health by preventing breakage, but it doesn’t affect the rate of growth, which happens at the follicle,” notes dermatologist Dr. Shereene Idriss.

Bottom Line: Regular trims keep your hair looking healthy without speeding up growth. Trims help with hair length retention, not hair growth rate.

Myth #2: Are Expensive Hair Growth Products Better?

The Myth: High price equals high performance.

The Reality: Cosmetic chemist Ginger King explains, “Effective hair growth products rely on proven ingredients like minoxidil, biotin, or peptides—not the price tag.”

Advice: Focus on the ingredient list and clinical studies rather than packaging. Look for ingredients like minoxidil, biotin, and caffeine instead of trusting the price tag.

Recommendation:

The Ordinary Multi-Peptide Serum for Hair Density: Features ingredients like acetyl tetrapeptide-3, caffeine, and castor oil. Backed by user reviews (4.2⭐ on Sephora) for fuller-feeling hair. Ideal for budget-conscious users seeking density support.

Rogaine (Minoxidil): FDA-approved and clinically proven to stimulate hair growth and extend the anagen phase. Supported by decades of research, it remains the gold standard for treating hereditary hair loss.

Myth #3: Should You Wash Your Hair Every Day for Growth?

The Myth: Daily cleansing is essential for a healthy scalp.

The Reality: Over-washing can strip away natural oils, leading to dryness and breakage. Dermatologist Dr. Francesca Fusco advises, “Finding the right balance is key; most people do best with 2–3 washes per week.”

Tip: Adjust your routine based on your hair type and environmental factors. Over-washing leads to scalp imbalance, not faster growth.

Recommendation:

Briogeo Scalp Revival Charcoal + Coconut Oil Micro-Exfoliating Shampoo: Combines charcoal, tea tree, and coconut oil to gently exfoliate and rebalance the scalp. Highly rated (4.3⭐ on Sephora) for reducing itchiness and flakiness.

Myth #4: Do Natural Remedies Really Work for Hair Growth?

The Myth: All-natural ingredients are inherently safe and effective.

The Reality: Natural remedies such as aloe vera, castor oil, and rosemary oil have benefits, but results can vary. “Not every natural treatment works for every hair type, and some can even trigger sensitivities,” warns trichologist Anabel Kingsley.

Takeaway: Combining natural solutions with clinically proven treatments often yields the best results. Combine rosemary oil or aloe vera with clinical products for best results.

Recommendation:

Mielle Rosemary Mint Scalp & Hair Strengthening Oil: Blends rosemary and biotin for scalp stimulation. Rosemary oil has been shown in studies ( Panahi et al., 2015) to perform similarly to minoxidil. 4.5⭐ average from over 20,000 reviews.

Myth #5: Does Brushing Your Hair Stimulate Growth?

The Myth: Increased brushing boosts scalp circulation.

The Reality: Excessive brushing can cause damage, leading to breakage. Gentle scalp massages are a much more effective way to encourage blood flow without harming your strands.

Pro Tip: Use your fingertips or a soft-bristle brush to massage your scalp instead. Try a 3–5 minute scalp massage instead of brushing excessively.

Recommendation:

Heeta Scalp Massager Brush: Increases blood flow and enhances product absorption. Highly rated (4.6⭐ with over 90,000 Amazon reviews) and often recommended by stylists for gentle exfoliation and stress relief.
