TikTok has become the go-to destination for beauty trends—and when it comes to hair growth routines, creators are unlocking real results in front of millions. But which viral methods actually work, and which are just hype? We’ve dug deep into the most popular hair growth trends taking over TikTok in 2025 and paired them with scientific insights and dermatologist-approved tips. Here’s your ultimate guide to TikTok-famous hair routines you can try right now for longer, stronger, and healthier hair.

1. The Rosemary Oil Routine: TikTok’s Golden Elixir

Rosemary oil is TikTok’s Hair grow MVP. Users swear by its ability to stimulate hair follicles, reduce shedding, and promote thickness, and science backs them up.

How to Do It:

• Mix a few drops of rosemary essential oil with a carrier oil (like coconut or jojoba).
• Apply to the scalp and massage for 5 minutes.
• Leave overnight or for at least 30 minutes before washing.

💡 Pro Tip: For faster absorption, warm the oil slightly before applying and use a scalp massager.

2. The Inversion Method Challenge

With over 100M views, the inversion method is one of TikTok’s most viral hair hacks. It involves flipping your head upside down to increase blood flow to the scalp—enhancing follicle stimulation.

How to Do It:

• Sit in a chair and flip your head forward (like you’re touching your toes).
• Massage your scalp with oil or fingertips for 4–5 minutes.
• Do this daily for 7 consecutive days.

📈 Users report up to 1 inch of growth in a week, though individual results vary.

3. Rice Water Rinse: Ancient Hack, Modern Revival

The #RiceWaterChallenge has exploded on TikTok, with creators showcasing stronger, shinier, and faster-growing hair. It’s an ancient Asian remedy that’s rich in amino acids, vitamins B, C, and E.

How to Do It:

• Soak 1/2 cup of rice in water for 24 hours.
• Strain the water and apply it to clean hair.
• Leave on for 20–30 minutes, then rinse.

⚠️ Limit to once a week to avoid protein overload, especially if you have low-porosity hair.

4. Overnight Growth Serums + Satin Bonnets

TikTok influencers are swearing by overnight scalp serums paired with protective hair accessories. These routines are built around the idea that you can grow hair while you sleep.

TikTok-Famous Products:

• Caffeine scalp serums
• Peptide-based serums
• Niacinamide-infused treatments

Pair with:

• Satin or silk bonnet to reduce friction
• Satin pillowcase for extra protection

🛏️ Hack: Apply serum at night and wrap your hair to lock in moisture and boost overnight absorption.

5. Scalp Microneedling at Home

Once a clinical treatment, microneedling has hit TikTok with a vengeance. This technique creates micro-injuries in the scalp, encouraging collagen production and increased absorption of growth products.

How to Do It:

• Use a 0.5mm dermaroller once a week.
• Sanitize before and after use.
• Roll gently in vertical, horizontal, and diagonal patterns.
• Follow immediately with a growth serum (like rosemary or minoxidil).

⚠️ Never share devices and avoid use on broken or inflamed skin.

6. Hair Tea Sprays: A Herbal TikTok Favorite

Hair teas made from herbs like fenugreek, hibiscus, amla, and horsetail are now trending as daily hair mists.

How to Make It:

• Boil selected herbs in water for 15 minutes.
• Cool, strain, and pour into a spray bottle.
• Mist scalp and strands daily for shine and growth support.

🌿 Herbal teas are packed with antioxidants and can improve scalp health over time.

7. “Slugging” for Hair: The TikTok Deep Moisture Trick

Inspired by the skincare trend, hair slugging involves coating your hair in a thick layer of conditioner or oil and wrapping it overnight for extreme hydration.

How to Do It:

• Apply a hydrating mask or oil generously to mid-lengths and ends.
• Wrap hair in a silk scarf or shower cap.
• Rinse out in the morning with a gentle cleanser.

✨ Best for dry, brittle, or chemically treated hair in need of serious recovery.
