When it comes to growing thicker, healthier hair, your shampoo and scalp care routine matter more than you think. According to board-certified dermatologist Dr. Doris Day, certain formulas can actually support hair growth by strengthening strands, improving scalp health, and mimicking the signals your follicles need to thrive.
If you’re dealing with thinning or slow growth, these three derm-approved products stand out:
Women Are Swapping Their Boring Water For This Ice Pop Electrolyte Mix!
Redken Acidic Bonding Concentrate Shampoo
Dr. Day highlights this shampoo as a go-to for instantly fuller-looking hair. It contains citric acid, which helps reinforce weakened hair bonds—making strands feel stronger and thicker after just a few washes.
“It’s a hair bonder,” she explains, noting that many people notice their hair feeling significantly thicker—sometimes up to three to five times—after consistent use. It’s especially helpful if your hair feels fragile or damaged.
CeraVe Anti-Dandruff and Gentle Shampoo
For those looking for a more affordable option, Dr. Day points to CeraVe’s shampoo line. These formulas also include citric acid, supporting scalp health while gently cleansing. A healthy scalp is essential for hair growth, and addressing concerns like dandruff or irritation can create a better environment for follicles to grow stronger, healthier hair.
KeraFactor Shampoo and Serum
For a more advanced, “medical-grade” option, Dr. Day recommends KeraFactor. This system includes both a shampoo and a serum packed with peptides and botanicals designed to mimic natural growth factors in the scalp.
“These are signals your scalp needs for hair growth,” she explains. In her experience, patients often see noticeable improvements when adding this to their routine—especially if other methods haven’t worked.
The Bottom Line
Hair growth isn’t just about genetics—it’s also about creating the right conditions for your scalp and strands. From bond-repairing shampoos to growth-factor-inspired serums, these dermatologist-approved picks can help support thicker, healthier hair over time. Consistency is key, and pairing the right products with a balanced routine can make a visible difference.
