The factors affecting rabbit hair production are mainly the number of hairs per unit area of ​​the rabbit skin, the length and the diameter of the hair. The growth and dislocation of rabbit hair is seasonal. In the spring, 12% of hair follicles can not grow hair, and hair follicles that can not grow hair in summer reach 28% to 30%. Therefore, the yield of summer hair is the lowest throughout the year. Although the adverse effects of long light and high temperature exist simultaneously in summer, studies have shown that the main adjusting factor affecting the growth of rabbit hair and the hair replacement cycle is the change of light cycle, and the adjustment of light cycle on rabbit hair growth and hair replacement cycle is mainly through The pineal gland is secreted by melatonin. Melatonin synthesis and secretion in the night (short light) is high, in the day (long light) is low, the formation of circadian rhythm changes. This seasonal circadian rhythm of melatonin secretion transmits external time signals to the body, bringing the seasonal growth and fur change of the rabbit hair to be consistent with seasonal changes in the environment. In this way, under long summer light conditions, using long-haired rabbits treated with exogenous melatonin can artificially increase the content of melatonin in the body and give it a short light signal, which can activate already dormant hair follicles and promote rabbit hair. Growth, increase summer hair production. The melatonin treatment method is very simple: Long hair rabbits are implanted subcutaneously with 36 mg melatonin sustained-release preparations under long-light conditions. The best time to increase production is around the summer solstice. According to foreign studies, the total production of twice-shorned hair after 80 minutes of melatonin treatment was 17.7% higher than that of untreated rabbits. The production of first-class hair increased by 14.1% and the length of hair increased by 5.6%. In addition, after one week of melatonin treatment, the intake and body weight of long-haired rabbits increased significantly.
What is Fractional Co2 Laser
Fractional CO2 Laser generate beams of coherent light that are absorbed by the body's tissue as energy. The energy is delivered through a narrow range of wavelengths, and in the target area, the energy
causes temperature elevation which results in tissue evaporation or ablation. Fractional CO2 Laser effectively treat a broad range of skin conditions by removing all or part of the skin.
The body's natural healing processes then replace the damaged skin with new and healthy tissue.
How Does A Fractional CO2 Laser Work?
Fractional CO2 Laser produce light at a 10,600nm wavelength, which is absorbed by water in the tissue. The laser energy heats up the water until it reaches a boiling point causing the evaporation of the affected tissue. Some heat is absorbed by tissue adjacent to the ablated target area, causing tissue coagulation which induces hemostasis (the cessation of bleeding) as well as thermal stimulation of deep skin layers, which induces fibroblast stimulation and neocollagenesis (the formation of new collagen).
The laser beam can also be transmitted through a scanner which is a device used to further control the delivery of energy. The scanner regulates the configuration of energy delivered onto the skin, which can range from covering the entire treatment area or just a fraction of it (leaving the areas in between untreated); (also referred to as fractional ablation). The overall effect of ablation and coagulation, either full or fractional, is the removal of skin and the stimulation of the body to replace it with newer, younger skin.
