A recent paper regarding complex hair biology
Maintenance of tissue homeostasis is dependent on the communication between stem cells and supporting cells in the same niche. Regulatory T cells (Treg cells) are emerging as a critical component of the...
Thank you Feramon1 por the papers, in the second "
Interleukin-4 inhibits the melanogenesis of normal human
melanocytes through the JAK2–STAT6 signaling pathway.5
Downregulation of IL-4 caused by dupilumab may explain this
phenomenon. However, we could not completely exclude that

Good journey.
My advice is ask ourselves regarding the special pattern of common hairloss and the diferent incidence between sexes as aid to know about this maladie.
RU grow hair in monkeys?
Human scalp hair is more complexe than primates.
BTW any shoemaker know that only pig, primates and human skin/leather is similar respect to hair, Splits of these leathers have holes in it due hair fibre and dermal papila is located in the dermis and need trespass, in...
Exactly, stress acts producing gray hairs and the process can not be reverted, gray hairs are gray in all hair fibre and from the begining have not melanins. It is designed before hair emerge. It is orchestated in the hair cycle before. It is interesting that hair is envolved in a tupid neuron...
Interesting, but always need ask ourselves, common hair loss have a secial pattern. There are differences on the pH levels in scalp?
My theory stablish that pH in pilosebaceous units came more acidid and oxidized in bald areas due problems with sebum .

Abstract
While popular belief harbors little doubt that perceived stress can cause hair loss and...
The Hamilton's study needs take in account with a picth of salt due important androgens for hair are synthetized in the pilosebaceous unit, not in adrenals.
