TLDR Hair growth is controlled by cycles influenced by hormones and various signals.
This review focused on the regulation of hair growth, highlighting the cyclic transformation of hair follicles through the resting (telogen), growth (anagen), and regression (catagen) phases. The anagen phase involved rapid proliferation of follicular keratinocytes, leading to hair shaft elongation and thickening. The cyclic changes required rapid remodeling of epithelial and dermal components and were controlled by various factors, including sex hormones, neurotrophins, FGF, TGF, BMP, VEGF, Sonic Hedgehog, and other signaling pathways.
