what are some of the LHR machines on the market?
there are lots of laser out in the market and it's hard to distinguish between lasers that are used for skin rejuvenation treatments, and those meant for removing unwanted hair
so be very careful!

IPL vs DIODE
Alexandrite & Diode --> single light wavelength concentration
IPL --> use a full/broad spectrum of light wavelengths
some patients and professionals claim that the IPL's greater wavelength spectrum equals less precision and less control, which could mean an increased risk of burns and hair removal side effects with misuse.
it is popular in the market because it is very much cheaper compared to a diode.
be aware that hair removal systems that use traditional incoherent light (highly concentrate beam) for treatment (Intense Pulse Light/IPL) are not true hair removal lasers. a serious flaw with these systems is that they lack the laser's ability to produce a selective bandwidth of light that will only affect the hair shaft (selective photothermolysis). these devices produce a wide bandwidth of light that can heat up all of the surrounding tissue. true lasers usually achieve better and faster results for hair removal purposes.
IPL is not a LASER
As per US FDA, Intense Pulsed Light (IPL) is not a laser.... technically doesn't contain a laser. They use use xenon flash lamps that emit full spectrum light. In the US, IPL is sometimes called as "phototricholysis" or "photoepilation"... but now they are commonly (but incorrectly) referred to as "laser hair removal".
Permanent Hair removal vs Permanent Hair Reduction
US FDA ONLY allows the term "permanent hair removal" for ELECTROLYSIS. so be careful of false marketing/sales strategies. Laser = Permanent Hair Reduction

what not to do before LHR
- no waxing/plucking or removing hair with the root 4-6 weeks before and throughout the course of treatment
what to expect after LHR
- shedding (hair will fall off naturally) will start 1.5 weeks after your treatment and will last until 3.5 weeks (that's why it is recommended to go back after a month so that the shedding process is completely done;) )
- you will notice that hair looks like growing so fast, these are the hair that have been treated and is just coming through the skin to shed.
- exfoliating and/or scrubbing gently in the shower can help speed up the process (scrubbing is also healthy because it promotes healthy blood circulation)
- after shedding, you might experience little black dots still “stuck” in the skin. these are commonly referred to as pepperspots and will shed eventually, but might take a bit longer. exfoliate to help those out as well.
some people may experience the following potential temporary side effects
- redness for up to 3 days
- swelling around mouth of follicle for up to 3 days
- tingling or feeling of numbness
the following rare side effects are indicative of inappropriate laser type and/or settings
- crusting/scab (brown spots)
- purpura (purple coloring of the skin)
- temporary pigment change (hypopigmentation or hyperpigmentation)
what if you didn't expect shedding?
- the settings used might have been too low and you should inform your doctor that it didn’t happen.
- also, if you feel that a lot of hair didn’t shed, the doctor might have missed those parts
why do we need to have consecutive monthly treatments during the initial phase?
hair grows in 3 phases and is killed in the first anagen (active growing phase). several treatments are needed to target ALL hair in the active growth phase. after completing or so, patients should experience a considerable percentage of hair reduction.
anagen (active) is the growing phase or when the hair fiber is produced. during this time the hair contains a lot melanin thus the pigment of the color of your hair
catagen (club hair) is the period of controlled regression of the hair follicle. this is when the lower part of the hair stops growing, but does not shed, and the follicle is reabsorbed.
telogen (tired) is the last of the hair growth cycle. this is resting phase/dormant stage. the old hair falls out in preparation for the development of a new anagen hair.
after completing sessions... are we totally hair free?
NO! with laser we won't be totally hair free. only electrolysis will make us totally hair free! we will be hair free for a period of time. but it doesn't mean, we wasted a lot of money and still we are not hair free. laser, slows down hair growth as well and the growth will be super fine (barely noticeable hair).
maintenance/touch ups/booster shots
after completing our sessions. we will have permanent hair reduction. for us to maintain it, we have to have booster shots as well. this could be 1 year or 2 years after your last treatment. how fast hair growth is depends from person to person. if you think, you it's reasonable to have another session, then go for a booster shot.
