Laser hair growth devices can have different effects for different types of hair loss. It is usually indicated for the following types of hair loss:
Hereditary hair loss (male and female pattern baldness): Hereditary hair loss is the most common type of hair loss and is usually caused by genetic factors. Laser hair growth devices may have some effect on hereditary hair loss, which can promote hair growth and enhance the health of hair follicles.
Sporadic alopecia (alopecia areata): Alopecia areata is localized hair loss that usually appears as round or irregular patches of hair loss on the scalp. Laser hair growth devices may be helpful for alopecia areata**, which can stimulate the growth of hair follicles and promote hair regrowth in areas of hair loss.
Early stages of hair loss: Laser hair growth devices often work better in the early stages of hair loss. When the hair follicles at the root of the hair have not completely decayed, the laser beam can stimulate their vitality and promote hair growth.
However, laser hair growth devices may be less effective or ineffective for:
Chronic hair loss: If hair loss has been going on for a long time and the hair follicles have been severely degraded or almost non-existent, the effectiveness of a laser hair growth device may be limited.
Scarring alopecia: Scarring alopecia is hair loss caused by damage to the scalp or scarring. Laser hair growth devices are often ineffective for this type of hair loss because the laser beam has difficulty penetrating the scar tissue.
Autoimmune alopecia: The mechanism of autoimmune alopecia such as alopecia areata, generalized lupus erythematosus, etc., is related to abnormalities in the immune system. Laser hair growth devices are only effective in these types of hair loss.
Laser hair growth devices may be beneficial for some types of hair loss, but they are not suitable for all types of hair loss. Before considering a laser hair growth device, it is best to consult a medical professional or **doctor to understand the individual situation and get the appropriate ** advice.
