Looking for a hair-growth serum that actually works? In a recent Allure article, Dr. Kiran Mian of Hudson Dermatology and Laser Surgery and other board-certified dermatologists shared their top recommendations and expert advice on what to expect from these products.
Dr. Mian specifically praised the Ranavat Fortifying Hair Serum for its lightweight texture and nourishing formula, which includes jasmine oil, amla extract, and sunflower oil. While serums can help improve scalp health and support hair growth, patience is key—results typically take about three months.
How Do Hair-Growth Serums Work?
The best serums contain proven ingredients like minoxidil, caffeine, biotin, peptides, and plant extracts to support hair follicles and promote stronger, thicker strands. However, they require consistent use to be effective.

- Best Budget Pick: The Ordinary Multi-Peptide Treatment – An affordable, effective option.
- Best for Sensitive Scalps: Vegamour GRO Hair Serum – A gentle, plant-based formula.
Dr. Kiran Mian’s Expert Advice on Hair Serums
Dr. Mian emphasizes that hair serums aren’t an instant fix but can play a key role in supporting scalp health and hair strength over time. She explains that the best formulas don’t just target hair strands but work at the root level, nourishing the scalp and follicles to create the optimal conditions for healthy growth.
For those struggling with hair thinning, she advises looking for ingredients like amla extract, peptides, and botanical oils, which help reduce inflammation, improve hydration, and protect against breakage. She particularly highlights Ranavat Fortifying Hair Serum as an excellent pre-shampoo treatment, noting that it’s easy to apply, lightweight, and effective without being greasy or sticky.
Dr. Mian also stresses that consistency is crucial. Many users expect immediate results, but she advises giving a serum at least three months before determining its effectiveness. In addition to topical treatments, she recommends maintaining a healthy scalp care routine, avoiding harsh hair treatments, and considering professional advice if hair loss persists.
