Not every hair restoration journey or hair loss prevention plan will involve transplant surgery or medications.

What Is Low-Level Laser Therapy For Hair Loss / Thinning Hair In Singapore?

Low-level laser therapy, also called LLLT, nourishes hair follicles by sending pulses of energy into inactive follicles. These pulses “spark” those dormant follicles back into a regrowth phase by kickstarting proper circulation and cellular respiration.

How Do Lasers Treat Hair Loss / Thinning Hair?

Hair follicles contain cytochrome C molecules that absorb red light. After red light is absorbed, these molecules are ‘activated’ and send off signals to the other cells in the hair follicle. The effects on the follicle include reduced inflammation and delaying apoptosis (programmed cell death).

The result is hair follicle that produces a stronger, more pigmented and thicker hair shaft, providing more aesthetic coverage.

LLLT is not a one-off treatment, and repeated treatments will be required to achieve the results on hair restoration and growth.

Am I Suitable For LLLT?

LLLT is typically painless and side effect free. However, LLLT has only shown benefit in sufferers of pattern hair loss i.e. male or female pattern hair loss.

It is recommended that you discuss your decision to commence LLLT with us.

Which LLLT Treatment Provides Safe, Effective Results for Hair Loss

iGrow® Home Hair Laser Device

What’s The Scientific Evidence For iGrow®?

The research into using LLLT for treating thinning hair is extensive. Clinical studies showing the effectiveness of LLLT for thinning hair go back more than 20 years and have been conducted and published by such places as The Wellman Center for Photomedicine, Harvard University, The American Society for Laser Medicine, International Society of Hair Restoration Surgeons and many others. The iGrow® itself was subjected to two double-blind clinical trials, which showed an average of 35%-37% increase in new growth in just 16 weeks. Both studies were published in a peer-reviewed medical journal, submitted to the US Government for review and were responsible for the iGrow®’s FDA and Health Canada clearances for treating genetic hair loss in men and women.

How Long Does iGrow® Take To Work?

Like any treatment, some people see results sooner than others but most notice an improvement within 3-6 months. Even strong, healthy hair typically grows only 1/4”-1/2” per month, so we recommend using the iGrow® for at least six months before evaluating how effective it can be for your type of thinning hair.

Why Should I Use iGrow® Versus Physician In-Office Lasers?

The iGrow® is one of the most powerful hair growth systems developed for home use, and has an equivalent output to most in—office hair lasers. Further, the iGrow®’s patented headphone design maintains a fixed distance of 3cm from the scalp. In addition, the iGrow® can be used conveniently at home, the office, or any convenient location while listening to your favorite music on your iPod® or MP3 player.

Why Should I Use iGrow® Versus Other Hand Held Devices?

The iGrow® is hands free, easy to use and it provides full scalp coverage. Compare that to moving a laser comb every 4 seconds for 20 minutes. The iGrow® has more light energy and provides the most consistent scalp coverage necessary for great results.

LLLT: Stand-alone Treatment or In Conjunction With Transplant Surgery or Medication

LLLT can be effective by itself, but it is also often used as a complement to transplant surgery or alongside medication such as Rogaine or Propecia.

After a hair transplant, LLLT helps bring blood, oxygen, and nutrients to balding areas, enhancing the effects of the surgery.

FAQ

When selecting an LLLT device, you should consider and compare specifications like:

  • coverage,
  • power output,
  • wavelength of light
  • and the manufacturer’s recommended usage.

These are what to look out for:

  • The device should be able to cover all areas of hair-loss affected scalp, e.g. a cap or helmet device.
  • The wavelength of light MUST be between 630-670nm to be effective.

Some devices are readily portable while others tend to be bulkier, choosing one that suits your lifestyle.

The hair-stimulating energy is delivered to the scalp through the use of specialized comb, caps, or domes.

All three of these delivery systems are effective and non-invasive, but one of them offers superior ease and convenience.

Laser domes are professional pieces of equipment, so a visit to the doctor is required to receive such treatment.

While laser combs can be used at home, the application and use of the comb can be cumbersome and time-consuming.

Laser caps, however, could not be easier to use. They are portable, hands-free, and they work.

There are a number of LLLT devices in the market, the popular ones being Capillus, iGrow, HairMax, just to name a few.

Red light from Laser and LED devices emitting 650—670nm wavelength light can stimulate cells within the follicle, as part of an effective LLLT hair treatment. The Laser light produces a specific wavelength that is believed to stimulate the hair follicle cells. The LED light uses a broader beam of gentle light energy to cover a wider area of the scalp. Combining the Lasers and LEDs offers the benefit of both light sources for men and women with androgenetic alopecia (thinning hair). But the proof is in the results. The iGrow® Hair Growth System has shown the highest percentage increase in new hair growth of any published clinical studies on light mediated hair growth.
Most LLLT devices use either LEDs or Lasers. The iGrow® by Apira Science, Inc. utilizes both high—quality Laser and LED light sources. This form of LLLT is effective for hair growth in men and women with genetic—based hair thinning/loss. Will all laser and light devices provide equivalent results on the scalp? No. Not all devices have the same power and energy output, and therefore will not yield the same results. Many devices only cover a limited area. Most of these devices require the user to manually move a hand—held comb or brush repeatedly over the scalp for 10—20 minutes at a time. This is tiresome and does not provide consistent application of the light. The iGrow® combines Laser and LED light in a hands—free automated device that is easy to use, while providing consistent scalp coverage in each 20—25 minute treatment session.

LLLT can be used with hair loss products Rogaine or Propecia. However the use of pharmaceuticals is not required to achieve results with the iGrow®. That’s what’s great about the iGrow®! It is a product that requires only a one—time investment. The iGrow® causes no side effects, isn’t messy, and is very easy to use.
There is no evidence that increased Low-Level Light Therapy (LLLT) will provide better results. LLLT should only be used as prescribed. Each LLLT session should be followed by a period of rest. This translates into alternating session days.
Hair loss is a progressive condition. If untreated, you can expect to lose more hair over time. After the initial 4 to 6 month LLLT treatment period, you should continue sessions once or twice per week to maintain your hair quality.
The iGrow® is intended to be used by men and women who are afflicted with androgenetic alopecia. LLLT hair treatment should be incorporated into your weekly preventative maintenance routine to preserve and strengthen existing hair and provide a healthy environment for continued growth.
LLLT is effective in men and women ages 18 and older.
No. After transplant surgery, it is important that your scalp does not come into direct contact with any foreign object. Many devices use teeth or spikes that are studded with a laser. You should not use such devices as they will damage your transplant. Instead, use a device that covers the entire scalp but does not directly touch the scalp. At the present time only the iGrow® by Apira Science is safe and effective for patients immediately following transplant surgery.
Yes. The iGrow® uses Class 3R Lasers which are recognized as safe by worldwide governing medical bodies. It meets the safety guidelines established by the United States and many foreign governments for safety. The iGrow® is manufactured according to ISO 13485, the most stringent standard for medical device products.
Only low-energy laser and LED light is used. Clinical studies have shown that Low-Level Light Therapy (LLLT) is safe. LLLT has been used for decades in hair restoration clinics. Be assured that the iGrow®’s non—invasive laser technology is perfectly safe.
Yes. The iGrow® is an effective treatment for hair loss in most women, or for thinning hair in women.
Yes! The iGrow® has been tested and FDA-cleared for treating genetic hair loss for both men AND women. In fact, results for women were slighter better than men’s results in the iGrow®’s clinical trials.
The iGrow® has been specially designed with safety features for at home, office and travel use, including a safety mechanism controlling both laser and LED devices. In addition, the iGrow® is designed so that it can only be turned on when it is firmly placed on your head. The iGrow® is a safe and effective laser hair treatment for use at home or while travelling.
Yes, the iGrow® requires no manual movement. Simply, place the iGrow® on your head, select one of 5 pre-programmed sessions and then sit back and relax. When will I know if iGrow® is working for me? Every person is different. However, within 12 to 16 weeks of using iGrow® as directed, most users report that they can see a positive change. The appearance of thicker, fuller, and healthier-looking hair is typical within 24 weeks, or 6 months of LLLT.
No. Testing and user testimonials have shown no side effects when utilizing the iGrow® with LLLT for hair growth.
Do I need to wash hair or use a special shampoo before using iGrow®?
The iGrow® is not recommended for those with severe hair loss.
The iGrow® uses clinical-grade components including laser and LED diodes which are tested at 10,000 hours, so it’s extremely unlikely that any of them will “burn out” even after many years of constant use. Of course, like all electronics the iGrow® is subject to things like a loose wire or simply a faulty power cord which is rare but can easily be handled by contacting iGrow®’s Customer Support. The iGrow® is also covered by a 1-year manufacturer’s warranty to replace a malfunctioning unit if needed, although it should last for years with proper care.
