Hair Loss is one of the primary causes of stress in people. Two out of every three men can expect to be bald, or show signs of balding, before they reach the age of 30. Laser Hair Therapy (LHT) or Low level laser therapy (LLLT) is a non-surgical, scientific approach in the cosmetic treatment of hair loss, thinning hair, and scalp problems that is being used all over U.S. for the treatment of hair loss. Laser hair therapy is similar to other treatments, such as Propecia and Minoxidil. Few patients tend to respond better than others. On the whole, it seems that patients who 'have more hair', perhaps in early stages of hair loss tend to have better results. Large-scale clinical trials have yet to be performed. However, many men and women are seeing positive results in their hair response to laser hair therapy. LHT has been medically tested for effectiveness and FDA-approved safe.

What is the cycle of hair growth?

Usually, hair grows for quite a few years and then falls out. The root then rests for many weeks before starting to re-grow into a new hair. This cycle continues throughout a person’s life. Nevertheless, with age, some people replace fewer or thinner hairs resulting in a thinner head and eventual baldness. Baldness does not occur because hair falls out; baldness is caused since it does not grow back.

What are the causes of hair loss or thinning of hair?

There are several reasons for hair loss and thinning of hair. Some of them include:

•  Heredity
•  Male Pattern Baldness
•  Diet
•  Medications
•  Postpartum Changes in women
•  Menopausal Changes in women
•  Excessive Chemical Processing
•  Stress.

Who are the best candidates for Laser hair therapy?

Laser hair therapy is best for:

•  Men and women of any ages with early to mid stages of hair loss.
•  Women who are experiencing a general thinning of their hair density.
•  Hair loss has not been for more than five years
•  Bald area is less than 4 inches across
•  Hair loss is mainly at the top of the head
•  Bald area has lots of tiny, fine hairs.

What is the basic concept of Laser hair therapy?

Laser hair therapy strengthens and regenerates hair roots. This slows, and in some cases, reverses the degenerative hair loss cycle. It is a non-surgical scientific method that helps in the treatment of hair loss, thinning hair, and scalp problems. Once the hair roots are dead, nothing can be done to restore them. So, the sooner treatment is started the better the results. The therapeutic pure red light provided by the low level, or "cold" laser, stimulates blood supply to the hair bulb and scalp, increasing the number of red blood cells that deliver vital oxygen and nutrients. The result is a restorative and reparative chain reaction that clears the debris from the hair shafts, swells the cortex, and closes the cuticle leading to a healthier scalp and hair that looks and feels softer, thicker, and shinier and is more manageable. Used in conjunction with specially formulated shampoos and conditioners, laser light therapy delivers amazing results.

What is the science behind Laser hair therapy?

• Laser light uses the scientific principle of ‘photo bio-therapy’. This process takes place when cells absorb light and restore it themselves.

• Laser light penetrates deep into the tissues of the scalp, stimulating micro- circulation of blood supply, cell metabolism and protein synthesis.
• Scientific studies suggest that this cellular and sub-cellular activity breaks helps to prevent hair loss.

How does the Laser work?

Based on the research, Laser works by the following mechanisms:

• Energization: This process converts laser energy into cellular energy. Laser light augment the energy available to cells so they absorb nutrients faster and eliminate waste products.
• Circulation: This augments blood and lymph circulation through a process called vasodilatation. Minute studies have revealed that laser increases circulation and oxygenation of the blood to the scalp and hair bulb. Lasers aid hair to improve in fullness, shine, body and suppleness.
• Vibration: One the soft tissue and fluid vibrations become asymmetrical, they can be brought back into “harmonization” by being irradiated with low level laser light therapy.

How is Laser therapy performed?

• Individual’s being treated for hair loss sit comfortably under the lasers.

• The laser smoothly delivers the photo bio-therapy to the scalp.
• The patients may read a magazine during treatments. There is no pain or discomfort from the therapy. Few patients may experience some scalp-tingling.
• The LHT non-surgical cosmetic treatment makes use of a device containing 110-160 therapeutic soft low light level lasers.
• LHT transfers light energy directly from 110-160 laser diodes covering the individual’s head.
• The visible red light from the laser’s hood travels several layers into the tissue without damaging the skin and scalp.
• Since, the laser light does not cut or burn the skin, the remedial light-energy is absorbed by the cells and the process of cell repair starts.
• The trick behind this noninvasive, non-chemical hair loss treatment works is by stimulating the production of energy at the cellular level, thus improving cell function.
• It is believed that laser hair therapy may increase blood flow to the treated area as well.

What are the benefits of Laser hair therapy?

The benefits of laser hair therapy are:

• LLLT Works for all types of hair loss.

• It is assumed that pulsed LLLT can encourage tissue repair and regeneration.
• Stimulates hair follicles and increases blood flow to the scalp
• Helps to stop hair loss and thickens existing hair
• Contrary to many treatments, laser energy works on all parts of the scalp
• When used post-operatively, the newly-transplanted hair follicles will grow quicker.
• European studies have shown that laser hair therapy stops hair loss in 85% of cases and stimulates new hair growth in 55% of cases.
• Patients who have used the therapy have reported that their hair looks and feels thicker, fuller and healthier and they have noticed improved hair growth.
• It is assumed that when both pulsed light is used in combination with the visible infrared red light spectrum, it might have value for different hair treatments which are becoming the focal point of marketing and research activities nowadays.
• Laser hair therapy costs less than alternative hair treatments.
•  It is drug-free and non-invasive.
•  This treatment has no pain and it is 100% safe.
