Frequently Asked Questions
Which serum is best for eyebrow growth?
The best eyebrow growth serums focus on key ingredients that protect existing brow hairs and stimulate new hair follicles. “Prostaglandin analogs are among the most potent options, working to lengthen the growth phase of hair. Peptides stimulate the dermal papilla cells in hair follicles to support growth and strengthen hair shafts, while biotin boosts keratin production for thicker, more resilient brow hairs. Panthenol (vitamin B5) conditions and moisturizes to prevent breakage, and castor oil, rich in ricinoleic acid, enhances circulation to the follicles, potentially stimulating growth,” says Dr. Brimhall. These ingredients help kickstart new hair growth and level up the fullness, strength, and density of your brows.
Do eyebrow serums really work?
Yes, brow serums can work, but results vary based on genetics, age, skin, and overall health. “Brow serums can effectively promote the growth of fuller, thicker brows by stimulating stunted hair follicles and nourishing existing hair shafts,” says Dr. Brimhall. However, success depends on the condition of your brows and body. For instance, regrowth may be impossible if scarring from overplucking or injuries has destroyed the follicles. Similarly, those with naturally sparse brows due to genetics or age-related slowdowns in the hair growth cycle might see more subtle results than younger individuals with healthier follicles. “Your hair, skin, and nails often reflect your overall health. If you notice significant changes in your brows, it’s worth investigating the root cause to fully benefit from any brow serum,” she says.
What actually helps eyebrows grow?
“A healthy lifestyle, staying hydrated, managing stress, and maintaining a nutrient-rich diet with proteins, vitamins, and minerals are crucial for overall well-being and can promote healthier eyebrows and hair,” says Dr. Kazlouskaya. However, she emphasizes not relying solely on lifestyle changes, as hair and brow loss can sometimes signal underlying medical conditions. “In some cases, the loss may be irreversible if untreated, or it could delay diagnosing significant issues like autoimmune diseases or chronic skin disorders. Consulting a board-certified dermatologist helps identify and address the root cause, preserving hair health and overall wellness,” she says.
