Laser hair removal is one of the best ways to help reduce unwanted hair. Laser hair removal targets your current hair follicles but new hair follicles can develop due to the influence of hormones and weight changes.
Hair Growth Cycle:- there are 4 stages
- Anagen- Growth Phase – It is a growing phase which lasts for 2-8 years. The length of this phase depends on your genetic profile and medication such as Rogaine help prolong this phase. During this phase, the cells in the root of the hair are actively dividing. Hair is most receptive to laser hair reduction at this stage.
- Catagen – Regression Phase- This is the regression phase and is a short phase. It usually lasts for about 2-3 weeks. During this phase, there is a change in the shape of the base of the hair. It detaches from the blood vessels that have been nourishing it. The base of the hair becomes club shape and then it enters the next phase. During this phase, the hair follicles retract from the dermal papilla. 5% of our hair is in this phase at any time.
- Telogen- Resting phase- This is the phase where the hair is preparing to fall out. Stress and conditions such as pregnancy can send a lot of your hair into this phase simultaneously. It lasts for about 3 months. About 10% of our hair is in this phase at any time.
- Exogen- Shedding Phase- Hairs are actively shed during this stage. In a normal healthy scalp, about 50-100 hairs can be shed per day.
Types of hair: there are two types of hair
- Vellus hair- this is very fine hair which is typically shorter and is also known as “peach fuzz.”
- Terminal hair- This is developed hair and is more coarse, firm and is known as “mature hair.”
The rate of growth of hair: Hair grows faster in the face than other parts of the body. For treating hair on the face, typically LHR is performed 4-5 weeks apart. Underarms and bikini areas are treated every 6-7 weeks since they grow slowly compared to the face. Extremities and trunk hair is usually scheduled 8-10 weeks apart.
The number of treatment sessions and the gap between them depends on the following factors:
- Color of hair and type of hair
- Area to be treated
- Hair coarseness
- Hair growth density
- Type of skin
Are all laser hair removal the same?
There are two machines predominantly used for hair reduction services: Laser and IPL.
IPL or Intense Pulsed Light is not a true laser as light is scattered whereas Laser hair removal is more specific. IPL also needs more sessions to get the same effect compared to LHR.
Pros of Laser Hair reduction:
- Very specific wavelength used depending on the skin type and customized to fit your skin
- Can be used with darker skin types
- Faster compared to IPL
- Fewer treatments required compared to IPL
Cons of LHR:
- More expensive compared to IPL
Pros of IPL hair reduction:
- More affordable compared to LHR.
Cons of IPL hair reduction:
- Can not be used on darker skin.
- Not effective in lighter hair
- Higher risk of burns
- Is it permanent?
Laser hair reduction is permanent hair reduction but hormones and weight fluctuations can cause hair to grow back. Hence maintenance(about once per year) is usually required after the first year.
- How many sessions do I need?
Most people respond in about 3-4 session but a few people may require more sessions(6-8).
- What are the risks?
Most significant risk is eye damage and goggles need to be worn specific to the wavelength used. Other risks include blistering, scarring, swelling, skin discoloration and burns in sensitive skin. It is normal for some redness and swelling after laser hair reduction.
- Does it hurt?
Pain is minimal and sometimes it feels like a rubber band snapping against your skin.
- Do I need to go and see a doctor or can I go in for the cheapest place I can find?
LHR is all about choosing the right laser for your skin and the right amount of energy to prevent complications.
- Will it work on my skin type and hair color?
Skin color is classified into 6 Fitzpatrick types with type 1 being lighter and type 6 being darker. Alexandrite or Diode laser is used for lighter skinned indiviuals where as Nd:YAG needs to be used on darker skinned individuals.
Blonde, grey, light red hair are difficult to treat compared to darker hair color.
- We customize the treatment solution for you by
- Changing the fluence of the laser
- Customizing the duration of the laser beam
- Choosing the appropriate laser for your skin type – Alexandrite vs nd:YAG 1064
- We understand that every person is different and some people will need 4-6 treatments for results where as others will need 6-8 treatments to see results. We believe in results and hence we only offer unlimited package(for one calendar year) per medical guidelines.
- You can select the area for treatment and we will offer unlimited treatments in the chosen area for one full year. The frequency of sessions will be based on medical guidelines.
Moveo is a unique laser technology based on 4 fundamental concepts: effectiveness, speed, safety and simplicity.
Like most other hair removal lasers, the Alexandrite 755nm laser is traditionally delivered in a shot shot-by-shot method. This universal method of laser delivery sees the Alexandrite lose a vast amount of energy during treatments, sometimes as high as 32%. This traditional procedure can also be a slow and sometimes, very uncomfortable treatment.
For the first time, practitioners can now treat every client, regardless of skin type, using a specialist Alexandrite 755nm ‘Moveo Pain-Free’ laser technology. This new and unique innovation works by delivering the Alexandrite laser at an ultra-high repetition rate, using a large 20ml contact-cooled sapphire tip which stays in continuous contact with the skin. This dramatically reduces the energy that is typically reflected by the skin when using a standard Alexandrite laser. This, therefore, allows lower fluences (energy) to achieve the target temperature required for clinically-effective, long-term hair removal results.
