Laser Hair Removal is on the Rise in Tokyo and Here’s Why
In Tokyo and around Japan, laser hair removal is becoming the go to for those seeking smoother skin without daily shaving.
And with the latest technological advancements capable of so much more, many prospective patients are now asking us this important question, “how long should hair be for laser hair removal?”
Therefore, we at BIANCA CLINIC in Tokyo thought it would be a good idea to address this issue in an informative piece designed to not only answer ‘how long should hair be for laser hair removal,’ but to provide expectations, and guidance on how to prepare, so that care is simple and consistent.
Lastly, for those who are confused by the area of expertise laser hair removal is in, it is not cosmetic surgery, just a “plain,” non-invasive treatment with minimal downtime that can be found at most medical spas and aesthetic surgery clinics.
Let’s Start with The First Question: “How long should hair be for laser hair removal?”
If laser hair removal in general is new to you, we shall quickly define it before moving on to the main topic. Basically, it utilizes light energy to target pigment in hair follicles.
By doing so it can slow or stop future growth with the best results when the hair root is intact. So, how long should hair be for laser hair removal?
Well hair above the skin should really be kept to a minimum and ideally shaved to skin level 12 to 24 hours before your appointment.
That leaves near-zero length, about 0 to 1 mm, which in turn reduces heat on the surface hairs, and focuses energy deep within the follicle.
How Long Should Hair Be for Laser Hair Removal: A Rough Guide to Treatment at a Medical Spa in Tokyo
Though every clinic may be different, follow the rules below to ensure a smooth before and after treatment:
- Shave the area you would like to treat around 12 to 24 hours before treatment. Aim for a close-shave level of hair so 0 to 1 mm of hair above the skin.
- Do not wax, tweeze, or thread for 3 to 4 weeks before your session as you need the hair follicle intact to undergo laser hair removal.
- Avoid depilatory creams for 72 hours prior as well because they will irritate the skin and increase discomfort during the procedure.
- If you cannot shave, for instance if you have a very sensitive facial area, then a light trim should be sufficient. We recommend getting the hair length down to about 1 mm and if necessary, let the clinician refine the shave.
- Arrive with clean, product-free skin so that no oils, makeup, or deodorant is actively in the treatment area.
Why Length Matters When It Comes to Answering How Long Should Hair Be for Laser Hair Removal?
A lot of patients not only ask us about “how long should hair be for laser hair removal,” but even more so ask, “why does it matter?”
And we usually offer two answers, one of which is more scientific and the other, easier to understand.
But if we were to blend both of those answers together it would be that lasers are absorbed by melanin in the hair shaft and bulb, so long surface hairs waste energy and can increase the chance of singe or odor.
We also would explain that by fully removing hair from the root via waxing leaves too little for the laser to target.
That is why keeping hair extremely short but present focuses light where follicles actually are, and several studies and clinical experience show a 70 to 90% average reduction after a full series of treatment (typically 6 to 8 sessions), with maintenance scheduled when needed over time.
Laser Hair Removal vs. Alternatives at a Medical Spa or Cosmetic Surgery Clinic
- Laser hair removal (typically at a medical spa) provides a high, long-term reduction in hair with around 70% to 90% reduction after a series of treatments. It also comes with moderate upfront costs and low maintenance. The sensation is similar to quick heat snaps with minimal downtime present, but some transient redness or follicular bumps are possible. Having treatment at a reputable clinic ensures safe and conservative settings (which will in turn reduce side effects).
- IPL: This is a different kind of laser that utilizes a broad-spectrum light. It can work well but often requires a few more sessions and more maintenance compared with plain lasers, with a sensation and pinkness that is similar.
- Waxing/sugaring: This is a well-known treatment for hair removal and can provide immediate smoothness but is short-lived. There is a higher risk of ingrown hairs occurring and irritation, with most patients choosing to undergo waxing/sugaring every 3 to 6 weeks.
- Shaving/creams: By far the cheapest way to remove hair but daily or weekly upkeep is required. Of course, the risks are pale in comparison but there are some minor risks of cuts (particularly around the neck), or irritation with creams.
- Electrolysis: This is a permanent treatment per follicle and is excellent for light hair but can be a bit time-intense and comes with higher cumulative cost for larger areas.
- Cosmetic Surgery: Not a standard method for hair removal but does appear in some aesthetic surgery plans. Cosmetic surgery clinics generally address shape or scaring, while laser manages hair and is far more complementary.
