If you’ve been struggling to grow your hair past a certain length, you’re not alone. Breakage, slow growth cycles, and lack of proper care can keep your strands stuck in a frustrating loop. The good news? With the right products and a consistent routine, you can see noticeable growth in just 30 days.
This guide breaks down the best hair growth products (scientifically backed and influencer-approved) and provides a step-by-step weekly routine to maximize results. Let’s dive in.
The Science-Backed Products for Maximum Hair Growth
1. Scalp Stimulating Oils (The Foundation of Growth)
Your scalp health determines your hair’s growth potential. These oils deliver nutrients directly to hair follicles:
- Rosemary Oil – A 2015 study in Skinmed Journal showed rosemary oil performed equally to minoxidil for hair regrowth. It contains ursolic acid which improves circulation to follicles. For best results, mix 5 drops with 1 tbsp jojoba oil and massage for 5 minutes before washing.
- Castor Oil – The high concentration of ricinoleic acid (90%) makes this a powerhouse for growth. It penetrates the hair shaft to prevent protein loss. Jamaican black castor oil (like from Tropic Isle Living) has added ash for extra thickening benefits.
- Peppermint Oil – A Korean study found 3% peppermint oil increased hair growth by 92% after 4 weeks. The menthol creates a tingling effect that boosts blood flow. Always dilute with a carrier oil to avoid irritation.
Pro Tip: Create a weekly growth oil :
- 2 tbsp castor oil
- 1 tbsp argan oil
- 5 drops rosemary oil
- 3 drops peppermint oil
2. Clinical-Strength Hair Growth Serums
For targeted treatment, these serums deliver active ingredients where you need them most:
- The Ordinary Multi-Peptide Serum – Contains Redensyl, Procapil, and Baicapil – three clinically-studied complexes that reduce shedding by up to 76%. The lightweight formula won’t weigh hair down.
- Kerastase Genesis Serum – Contains edelweiss extract, ceramides and caffeine which strengthen hair roots and stimulate growth. Clinical tests show 73% less hair fall in 6 weeks, with hair appearing thicker and healthier
- Vegamour GRO+ Advanced Serum – Uses CBD and mung bean to reduce cortisol-related hair loss while supporting follicle health. The vegan formula shows visible results in 30-90 days.
Application Tip: Apply serums to clean, towel-dried hair focusing on problem areas. Use a scalp massager to enhance absorption.
3. Repairing Shampoos & Conditioners
Preventing breakage is crucial for retaining length. These salon-quality options actually work:
- Olaplex No. 4 & 5 – The patented bis-aminopropyl diglycol dimaleate repairs broken disulfide bonds from heat, color, and mechanical damage. Use 2-3x weekly for best results.
- Mielle Rosemary Mint Line – Contains biotin, peppermint, and rosemary in a sulfate-free formula that cleanses without stripping. The conditioner has amazing slip for detangling.
- Briogeo Don’t Despair, Repair! (shampoo & conditioner)- Features a unique blend of rosehip oil, B vitamins, and algae extract to strengthen from root to tip. The deep conditioning mask is perfect for weekly treatments.
Washing Technique: Focus shampoo on scalp only, letting suds clean lengths. Always follow with conditioner on mid-lengths to ends.
4. Essential Supplements for Faster Growth
Nutritional support makes a dramatic difference:
- Nutrafol Women – The marine collagen, saw palmetto, and ashwagandha address multiple causes of hair thinning. Clinical studies show 80% improved growth after 6 months.
- Viviscal – Contains AminoMar marine complex which provides the building blocks for keratin production. Users see results in 3-6 months.
- Moon Juice SuperHair – Features adaptogenic herbs like astragalus and tremella mushroom to support growth during stress. The tasteless powder mixes easily into drinks.
Supplement Tip: Take with food for better absorption, and be consistent for at least 3 months to see full results.
