Did you mean Reticular Fibroblasts?

Glossary Reticular Fibroblasts

Reticular fibroblasts are specialized cells found in the connective tissue that play a crucial role in the formation of the extracellular matrix, particularly in lymphoid organs. In the context of hair loss, these fibroblasts contribute to the structural integrity of the dermal papilla and surrounding tissues, which are essential for hair follicle development and cycling. Key distinguishing characteristics include their ability to produce collagen and other matrix components, influencing the overall health and function of hair follicles. Dysfunction or alterations in reticular fibroblasts can lead to impaired hair growth and contribute to various forms of hair loss.

community Minoxidil inhibits lysyl hydroxylase which is needed to produce collagen. If I take 2,5...5 mg of minoxidil every day can I cause my skin to age prematurely?

32 upvotes 1 year ago

Oral minoxidil is effective for hair loss and unlikely to significantly affect collagen synthesis, making it a safe option without causing premature skin aging. Users report positive hair regrowth without noticeable skin aging.

community Everything you ever wanted to know about Pelage Pharma's PP405: how it works and what to expect

126 upvotes 2 months ago

PP405 may encourage earlier hair growth and slightly increase visible hair count but does not reverse hair follicle miniaturization in male pattern baldness. It does not address damage to the dermal papilla or broken Wnt signaling.

community New Peer-Reviewed Publication Further Validates RepliCel's Use of Dermal Sheath Cup Cells to Treat Pattern Baldness - Paper entitled "Hair Follicle Dermal Stem Cells Regenerate the Dermal Sheath, Repopulate the Dermal Papilla, and Modulate Hair Type" published journal Developmental Cell

13 upvotes 11 years ago

A new treatment using dermal sheath cup cells may regrow hair and could require repeat treatments every 8 years. Users discuss ongoing trials and plan to use finasteride and minoxidil until the treatment is available.
