Laser hair removal works well for people with dark hair and light skin, but it's less effective for light hair or dark skin; improvements are expected.

The study found that long-term sun exposure does not significantly affect follicular plugs on the scalp, and the scalp's appearance is unique compared to other body parts.

Wait 3 months after COVID-19 before trying assisted reproduction and further research is needed on COVID-19's effects on male hormones and fertility.

Platelet-Rich Plasma (PRP), a substance from a patient's own blood, can stimulate hair regrowth in people with Androgenetic Alopecia (AGA) who haven't had success with other treatments, but more research is needed to optimize its use.

COVID-19 and hypopituitarism (reduced pituitary gland function) are linked, with the latter's related health issues potentially worsening COVID-19 outcomes, and COVID-19 possibly increasing risk for pituitary complications.

A baby boy with 13q deletion syndrome had eye cancer, a woman's vision improved after stopping a breast cancer drug, a man developed cataracts from using Propecia, and a rare skin disorder called Lipoid Proteinosis was discussed. Also, a tool called OCT is useful for diagnosing macular diseases.

The paper suggests that hair loss might be caused by skull growth, not just DHT's effect on hair follicles, and calls for more research.

Platelet-Rich Plasma (PRP), a protein-rich extract from a patient's blood, shows promise in improving hair density, thickness, and quality, but the best method of use and number of treatments needed for noticeable results are still unclear.

A protein called EGFR protects hair follicle stem cells, and when it's disrupted, hair follicles can be damaged, but blocking certain pathways can restore hair growth.

People with atopic dermatitis have more CD4+ T cells that respond to a certain bacterial lipid, which may play a role in the skin condition's inflammation.

Researchers developed a new way to measure gene activity in single hair follicles and found that a specific gene's activity changes with different amounts and times of treatment.

Mice with a changed Hr gene lose and regrow hair due to changes in the gene's activity.

R-spondin2 may help treat hair loss, gene differences could explain baldness, a peptide's regulation is linked to psoriasis, B-defensin gene copies may affect a skin condition's risk and severity, and potential markers and targets for alopecia areata were identified.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

The study found that two enzymes linked to hair loss are located in different parts of the scalp, supporting a common treatment's effectiveness.

Male skin gets drier and more alkaline as it ages, which may need different skincare than women's skin.

Different species and human skin models vary in their skin enzyme activities, with pig skin and some models closely matching human skin, useful for safety assessments and understanding the skin's protective roles.

Psychotropic medications can cause skin reactions, including severe conditions like SJS and TEN, and it's important for psychiatrists to recognize and manage these side effects.

A boy with chromosome 13q deletion syndrome developed eye cancer, a woman with breast cancer lost vision due to a rare side-effect of her treatment, a man's vision worsened after using a hair loss drug, and two rare disorders were discussed. Optical Coherence Tomography is useful for diagnosing and monitoring these conditions.

The Brazilian Society of Dermatology agrees that oral isotretinoin is effective for acne and other skin conditions, and it's safe when monitored, but more research is needed on dosing and duration.

The study found that nerve signals are stronger when there are more connection points, but not necessarily denser, along the nerve's path in the spine.

Blood tests can help understand the genetic differences in people with alopecia areata, including how severe it is and if it's inherited.

Many people experience hair loss after weight loss surgery, especially younger women, and it's linked to lower levels of zinc, folic acid, and ferritin.

Some congenital hair disorders improve with age and can be managed with treatments like minoxidil, retinoids, supplements, and gentle hair care, but there's no cure.

Blocking 5α-reductase can harm memory and brain structure, and increase harmful brain changes in male mice used for Alzheimer's disease research.

In 2017, Spanish dermatologists commonly prescribed topical minoxidil, oral finasteride, and nutricosmetics for hair loss, with oral contraceptives also used for premenopausal women. Less common were oral dutasteride, due to side effects, and newer, more expensive treatments like topical finasteride and Low-Level Laser Therapy. The conclusion is that there's a need for prescription guidelines due to varied treatment approaches.

Dihydrotestosterone (DHT) is crucial for conditions like male-pattern baldness and acne, and measuring a byproduct, androstanediol glucuronide, is a better way to assess DHT's effects than DHT blood levels.

Hair follicles affect how well small molecules can pass through the skin, and this varies depending on the molecule's features.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Researchers created a model to understand heart aging, highlighting key genes and pathways, and suggesting miR-208a as a potential heart attack biomarker.
