Hair growth occurs in cycles: the anagen (growth), catagen (transition), and telogen (resting) phases. Most hair growth products work by extending the anagen phase and providing essential nutrients to the follicle.
Understanding Hair Growth: Expert Insights
According to the British Association of Dermatologists, hair growth products typically work through these key mechanisms:
- Extending the anagen phase – Keeping hairs in the growth phase longer
- Stimulating follicles – Increasing blood flow to the scalp
- Providing essential nutrients – Supporting healthy hair production
- Strengthening existing hair – Reducing breakage for apparent fuller growth
Key Ingredients to Look For In Hair Growth Products
Consultant dermatologist and hair specialist Dr. Sharon Wong said on Cosmopolitan UK: “Many hair growth serums contain peptides, amino acids and conditioning agents such as hyaluronic acid. These have an aesthetic effect on the hair that’s already on your head, giving it more volume and plumping up its fibres to make them look and feel thicker.” (1)
These ingredients also have ample clinical research on their hair growth effectiveness:
- Minoxidil – The only FDA and MHRA-approved ingredient for hair regrowth, with over 40 published studies supporting its efficacy
- Caffeine – Research published in the International Journal of Trichology shows it stimulates follicles and extends the hair growth phase
- Biotin – Essential B vitamin that strengthens hair structure, with deficiency strongly linked to hair loss in multiple clinical studies
- Rosemary oil – A 2015 study in Skinmed Journal showed it to be as effective as 2% minoxidil
- Peptides – Signal proteins that encourage hair follicle activity, backed by emerging research in the Journal of Cosmetic Dermatology
- Capilia Longa – Improves circulation to follicles, supported by research by Vytrus Biotech
- Ketoconazole – Anti-fungal that creates a healthy scalp environment, with studies in the British Journal of Dermatology supporting its role in hair growth

- Cleanse while stimulating the scalp
Study insight: Research from the University of Manchester demonstrated that caffeine-infused shampoos like Watermans can penetrate the hair follicle and remain active even after rinsing

How to Choose the Right Hair Growth Product: A Methodical Approach
Dr. Jonathan Steel, Head of Research at the UK Institute for Trichological Studies, recommends this evidence-based selection process:
- Identify the cause of hair loss – Different products target different types of hair loss; consult with a professional for accurate diagnosis
- Review clinical evidence – Prioritize products with published research supporting their efficacy
- Consider hair type and sensitivity – Some formulas work better for certain hair textures and scalp conditions
- Evaluate application requirements – Products that fit easily into your routine are more likely to be used consistently
- Assess value rather than just price – Consider concentration of active ingredients and duration of supply when comparing costs
Frequently Asked Questions About Hair Growth Products
How long does it take to see results?
According to a meta-analysis published in the British Journal of Dermatology, most hair growth products require 3-6 months of consistent use before noticeable results. Dr. Rachel Green, Consultant Dermatologist at Royal London Hospital, explains: “The hair growth cycle takes time, and new hairs need approximately 100 days to grow to visible length.”
Are hair growth products safe?
The National Institute for Health and Care Excellence (NICE) guidelines indicate most over-the-counter hair growth products are safe for general use. However, products containing minoxidil may cause side effects like scalp irritation in approximately 7% of users. The MHRA recommends discontinuing use if irritation persists.
Do hair growth products work for everyone?
The British Hair and Nail Society reports that results vary based on:
- The specific cause of your hair loss
- How early you begin treatment
- Consistency of application
- Individual response to active ingredients
Research published in the International Journal of Trichology indicates success rates between 60-85% depending on the product and cause of hair loss.
Can I use multiple hair growth products together?
Dr. Michael Chen, PhD in Cosmetic Science from University College London, advises: “Many users see best results with a multi-faceted approach. Research shows synergistic effects when combining topical treatments with nutritional support. Always introduce products one at a time to monitor for any adverse reactions.”
