Hair growing method based on maternal hair stem cells and micro-needles

Abstract

The invention discloses a hair growing method based on maternal hair stem cells and micro-needles. A transdermal delivery device based on the micro-needles is used, tiny gaps in the scalp surface aremanufactured through the micro-needles, cuticle barriers are broken through, and the maternal hair stem cells and cell preserving fluid used for transdermal delivery are directly delivered to the corium layer to be absorbed, so that the maternal hair stem cells and the cell preserving fluid directly and effectively play a role; the maternal hair stem cells and the cell preserving fluid are smearedon the surface of scalp, so that the maternal hair stem cells and the cell preserving fluid slowly permeate into scalp dermis tissues to realize hair regeneration. According to the invention, tiny gaps on the surface of scalp are artificially manufactured by utilizing a nano micro-needle technology and are used for transdermal delivery of maternal hair stem cells and cell preserving fluid so as to adjust periodic transformation of hair follicles and promote hair regeneration.

Description

technical field [0001] The invention relates to the technical field of hair growth, in particular to a hair growth method based on hair mother stem cells and microneedles. Background technique [0002] Hair loss with age is a common human condition that is generally thought to be related to immune dysfunction. Hair loss is a disease characterized by hair loss. Hair loss will affect the health of patients. In addition, hair loss affects the appearance to a certain extent. In the era of universal beauty, once hair loss occurs, people will think it is a serious problem! Common types of hair loss include androgenetic alopecia, alopecia areata, psoriatic alopecia, scalp discoid lupus erythematosus (DLE), etc. The researchers have shown through experiments that the expression of the surface markers CK15 and CD200 of hair mother stem cells in the hair follicles of patients with scalp DLE Both significantly decreased or disappeared, suggesting that hair follicle stem cells were sig...

AI Technical Summary

Problems solved by technology

[0005] 2. The dermal papilla in the hair follicle is dysfunctional;

[0006] 3. Reduced hair follicle metabolism;

[0007] 4. The inflammatory response attacks and destroys the environment around the hair follicle;

However, transdermal drug delivery also has its disadvantages. The barrier function of the stratum corneum of the skin can intercept a variety of macromolecules, which greatly limits the application of transdermal drug delivery systems. Therefore, this barrier has become a major problem for transdermal drug delivery systems.
