Human hair's ability to get wet is complex and can change with treatments, damage, and environment.

Hair stem cell regeneration is controlled by signals that can explain different hair growth patterns and baldness.

Disulfide bonds affect the melting behavior of hair's crystalline structure, but hair retains some stability even after these bonds are broken.

Changing disulfide bonds in human hair affects its melting behavior and thermal stability.

Scalp massages and medical treatments for hair loss are more satisfying than folk remedies.

Hair regeneration needs dynamic cell behavior and mesenchyme presence for stem cell activation.

Two-photon microscopy helps observe hair follicle stem cell behaviors in mice.

3D microenvironments in microwells improve hair follicle stem cell behavior and hair regeneration.

Aging causes hair loss and graying due to stem cell decline and changes in cell behavior and communication.

Different ectodermal organs like hair and feathers regenerate differently, with specific stem cells and signals involved in their growth and response to the environment.

Light scatters differently from elliptical hair fibers than from circular ones, and a new model better predicts this behavior, especially for shiny highlights.

Most dogs have hair whorls on their chest and limbs, with shelter dogs and short-haired dogs having more chest whorls.

AFM helped show how hair changes under tension and the effects of damage and conditioner.

Moisture content significantly affects how human hair breaks.

Immune cells help regulate hair growth, and better understanding this can improve hair loss treatments.

Growing hairs are easier to pull out than resting hairs due to different anchorage strengths.

Chimp Haven uses a special system to check and improve the well-being of their chimpanzees, which could help other animal sanctuaries too.

Fat tissue under the skin affects hair growth and aging; reducing its inflammation may help treat hair loss.

Injury changes how hair follicle stem cells behave, depending on the hair growth stage.

Power-enhancing drugs can cause mood swings, aggression, anxiety, and physical side effects, questioning their overall benefits.

Misbehaving hair follicle stem cells can cause hair loss and offer new treatment options.

Hair loss in male pattern baldness is linked to changes in immune cell behavior around hair follicles.

T cells with memory features grow in number and gather around hair follicles when there are not enough immune cells.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Higher light doses cause more damage to hair follicles, predicting better hair removal results.

The conclusion is that the dermal papilla is crucial for hair follicle regrowth, and hair follicles undergo significant structural changes in addition to cell division during regeneration.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

Researchers developed a new model for more realistic computer graphics rendering of hair by considering how light scatters on hair fibers.
