Glossary Hair Direction

natural angle and pattern of hair growth

Hair direction refers to the natural angle and pattern in which hair grows out of the scalp. This can vary from person to person and can influence how hair is styled, how it falls, and how it responds to different haircuts. Understanding hair direction is crucial for professionals in hairdressing and dermatology to achieve desired styling results and to address issues like hair loss or scalp conditions effectively.

learn Hair Transplant

Hair transplantation moves DHT-resistant follicles from a donor area (back and sides of the scalp) into thinning or bald areas. The transplanted hair is generally permanent, though surrounding native hair can keep thinning.

Is a hair transplant painful? A hair transplant is generally comfortable due to local anesthesia, with mild post-procedure soreness possible.

learn Follistatin

glycoprotein that inhibits TGF-β and promotes hair growth by antagonizing activin

learn Osteopontin

signaling protein that, when suppressed, may grow hair by reducing inflammation and stem cell loss

learn Hair Fibers

cosmetic product that temporarily makes hair appear thicker

Do hair fibers really make thinning hair look fuller, or is it just an illusion? Hair fibers create an optical illusion of fullness but do not actually thicken hair.
How do you apply hair fibers correctly so they stay in place all day? Apply hair fibers to clean, dry hair and use a setting spray for better hold.
Can hair fibers be used along with medical treatments like minoxidil or finasteride? Yes, hair fibers can be used with minoxidil or finasteride without any chemical interaction.

community Diffuse thinning is a curse. You don't realize it's happening until way too late.

in Chat 141 upvotes 1 year ago

Diffuse hair thinning and treatments like finasteride and minoxidil. Early detection and treatment are crucial for effective management.

community First week finished on finasteride 0.5mg MWF

in Finasteride/Dutasteride 9 upvotes 1 year ago

The conversation discusses starting finasteride for hair loss, with the original poster noting reduced scalp itching and oiliness after the first week. Users share experiences with different dosages and schedules, concerns about side effects, and the potential impact on prostate cancer detection.

community Why do Hair Transplant procedures take a rectangle from the donated area?

in Transplants 6 upvotes 1 month ago

Hair transplants typically involve spreading follicle extraction across the back and sides of the head to maintain an even appearance, rather than taking a solid rectangle of grafts. FUT procedures, which involve taking a strip of skin, are less common now due to advancements in techniques like FUE, which heal well and are less invasive.

community Another mechanism to hair loss that isn’t talked about. Heavy metals and follicle waste.

16 upvotes 2 months ago

Hair follicles can store waste, potentially leading to hair loss, and treatments like DHT blockers and Minoxidil are suggested. Scalp inflammation and sensitivity to DHT also contribute to hair loss, and addressing these factors with a clinician is recommended.

community Hair falling out on Finasteride?

in Transgender 11 upvotes 4 months ago

Shedding is common when using finasteride and minoxidil, and it typically stabilizes after a few months, with potential regrowth following. Users report varying experiences, but shedding is generally seen as a normal part of the treatment process.
