What is a High-frequency Hair Treatment?

A high-frequency hair treatment operates by utilizing a high-frequency device for hair that generates a high-frequency current, typically in the range of 100,000 to 250,000 Hertz. This current is applied to the hair and scalp through a specialized electrode.

Here’s how it works:

  1. Stimulation of Hair Follicles: The high-frequency current stimulates the hair follicles, promoting blood circulation in the scalp. This increased blood flow nourishes the hair follicles, potentially leading to healthier hair growth.
  2. Improved Oxygenation: The treatment enhances oxygen levels in the scalp, which contributes to a more favorable environment for hair growth. Improved oxygenation supports cell metabolism and helps in removing toxins.
  3. Anti-Bacterial Action: HF treatments have an antibacterial effect, helping to reduce scalp infections and dandruff.
  4. Enhanced Absorption of Topical Products: The high-frequency current opens up the hair follicles and pores on the scalp, making it easier for topical treatments and hair care products to be absorbed.
  5. Strengthening of Hair: By promoting blood circulation and providing a nourishing environment, HF treatments contribute to stronger and more resilient hair strands.

How To Use High Frequency For Hair?

To effectively use a high-frequency machine for hair growth, attach the comb wand head to your device and ground it by keeping a finger on the comb until it contacts your scalp.

Once on the scalp, release your finger and gently comb through your hair, dividing it into 5-6 sections. Focus on the affected areas for 2-3 minutes.

Follow this with a thorough hair massage lasting 20-25 minutes. This comprehensive approach helps maximize the benefits of improved blood circulation and product absorption for potential hair growth.

Side Effects of Using High Frequency For Hair:

HF Hair treatments are generally considered safe when used as directed, but like any cosmetic or therapeutic procedure, there are some potential side effects. It’s crucial to be aware of these and take necessary precautions:

  1. Skin Irritation
  2. Dryness
  3. Overstimulation (Excessive use or high intensity leads to overstimulation)
  4. Not Suitable for Certain Conditions: (Individuals with epilepsy, pregnancy, or a pacemaker, should avoid using HF devices)
  5. Temporary Hair Shedding (This is often a temporary phase as new, healthier hair replaces it)
  6. Eye Exposure (HF devices emit visible violet light. Ensure that your eyes are adequately protected during the treatment to prevent any potential eye strain or discomfort)

How Often Should You Do High Frequency for Hair?

It’s generally recommended to use a high-frequency device for hair growth 1 to 3 times per week. Consistency is key, but the exact frequency may vary based on individual needs and the specific guidelines provided by the device manufacturer.

Overuse potentially leads to overstimulation, so it’s essential to follow the recommended duration and intensity settings.


Consider these aftercare tips for HF hair treatment:

  • Moisturize the Scalp: Apply a non-greasy moisturizer to combat dryness and maintain scalp hydration.
  • Avoid Sun Exposure: Protect the scalp from direct sunlight immediately after treatment.
  • Use Gentle Hair Products: Opt for mild, sulfate-free shampoos and conditioners to maintain a gentle scalp environment.
  • Wait Before Washing Hair: Wait at least 24 hours before washing hair to allow product absorption.
  • Monitor for Irritation: Be attentive to signs of irritation, redness, or discomfort, and discontinue if needed.
  • Resume Regular Hair Care: Return to your regular hair care routine, incorporating products that support scalp health.
  • Limit Heat Styling: Minimize heat styling to prevent additional stress on the hair.
  • Stay Hydrated: Drink enough water to support overall hydration, benefiting hair and scalp health.
  • Consult a Professional: If concerns or unexpected side effects arise, consult a healthcare professional or dermatologist for guidance.

Can I Wash My Hair After High Frequency Treatment?

It’s generally advisable to wait at least 24 hours before washing your hair after a HF treatment. This allows any products applied during the treatment, such as conductive gels or serums, to be fully absorbed.

Washing your hair too soon after the treatment diminishes the potential benefits of the high-frequency session.


High-frequency hair treatments boost hair health by improving blood flow, reducing hair loss, and promoting stronger strands. To use it, attach the device, comb through your hair, and follow with a massage.

Benefits include better circulation, antibacterial effects, and enhanced product absorption. Be cautious of potential side effects like skin irritation. Afterward, moisturize, avoid sunlight, and wait 24 hours before washing.

Use the treatment 1-3 times weekly, and consult a professional if needed. Overall, it’s a simple addition to your routine for healthier, resilient hair.
