Stress may affect hair growth by influencing hair follicle development and could contribute to hair loss.

Stress can stop hair growth in mice, and treatments can reverse this effect.

Activating β-catenin increases melanocytes and decreases Schwann cells.

Certain daily habits like stress, diet, and sleep can affect the severity of hair loss in alopecia areata.

Metformin helps manage polycystic ovary syndrome by improving insulin resistance and ovulation, but more research is needed on its full effects.

The document concludes that understanding genetic mutations in the PI3K-AKT-mTOR pathway can lead to better diagnosis and treatment for certain genetic skin disorders.

The document concludes that careful history and physical exams are crucial for accurately diagnosing polycystic ovary syndrome and distinguishing it from other similar conditions.

Mutations in the CYP21A2 gene are not a major factor in causing PCOS.

Adequate vitamin D might lower, and high hair chromium might increase DNA damage in obese women.

People with atopic dermatitis are more likely to develop other skin conditions due to shared genetics and immune pathways.

The skin systems of jawed vertebrates evolved diverse appendages like hair and scales from a common structure over 420 million years ago.

Ozone therapy might improve cancer treatment and reduce its side effects.

Metformin and rosiglitazone improve blood vessel function in women with PCOS, with metformin also reducing insulin resistance and testosterone levels.

Metformin helps with menstrual cycles and insulin levels in PCOS but is less effective for hair growth, diabetes prevention, and weight loss, and may improve fertility and reduce diabetes risk.

Acne patients' skin, both with and without lesions, shows a strong immune response and higher antimicrobial activity.

Artificially inducing hair regrowth in mice can change the normal pattern and timing of hair growth, with minimal color differences between old and new fur.

Constant light exposure during pregnancy changes newborn rabbits' skin, affecting hair follicles, skin thickness, and pigment cells.

Low-dose anti-androgen drugs and certain drug combinations are effective for hirsutism, and insulin sensitizers show promise, especially for those with polycystic ovarian syndrome.

Obesity changes androgen levels in women with PCOS, leading to higher testosterone relative to androstenedione.

The article helps identify common, non-harmful skin conditions in newborns to avoid undue concern and treatment.

Some women with PCOS have CYP21 mutations and IRS1 variants, but these genetic factors are not major contributors to PCOS.

HIV can cause unusual and severe skin problems that are hard to treat.

The skin's basement membrane has specialized structures and molecules for different tissue interactions, important for hair growth and attachment.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.

Skin fat helps with body temperature control and has other active roles in health.

The conclusion is that understanding how hair follicle stem cells live or die is important for maintaining healthy tissue and repairing injuries, and could help treat hair loss, but there are still challenges to overcome.
