Second hair needs intensive and special care, especially after the summer. The gfh, Society for Hair Aesthetics, gives tips on how to care for a second hair in the bathroom at home: Summer is coming to an end and often the hair has suffered from high temperatures, strong sun and UV radiation. Now it's time again: get to the hair care! For people who rely on hair replacements due to hair loss, this means a little more than just jumping in the shower. Scalp protection and professional care It is important to use the right hair replacement care products, because normal hair care products are only suitable for natural hair that has grown, but not for hair replacement. Special products ensure a long life for the hair replacement. The overall durability of the hair replacement depends on how often the hairpiece or wig is worn and how professionally it is treated and cared for. A permanent hair integration, for example, has to be removed and reattached every four to five weeks, since your own hair continues to grow. Under these conditions, a hairpiece can last between eight and ten months. Second hair: washing, caring for, styling Basically, it is important to distinguish whether the wig or hairpiece is made of real hair or synthetic fibers. Because the requirements for care and handling are fundamentally different. Real hair is basically treated like your own hair: it can be washed, blow-dried, treated with curlers and straighteners, even dyed and permed. However, as with natural hair, the hairstyle only lasts a few days. Human hair care - this is how it works:

Celebrity hairstylist Jay Small shares the simple ways men can bulk up thin strands and hide hair loss If you're losing your hair, going in for a haircut might feel like the last thing you want to do. But a smart, stylish cut can make thinning hair appear fuller, according to celebrity hairstylist Jay Small. Small has two decades of experience that includes work with celebrities like Matt Damon, Luke Grimes, and Noah Centineo. He also cofounded Arey, a dietary supplement and hair serum brand for aging and graying hair. The stylist told Insider that "hair thinning and hair loss for men, specifically," is the most common issue he encounters at the salon. Here are his top tips for making thinning, aging hair appear fuller and healthier. A comb-over can look chic if done properly Don't dismiss the comb-over, Small said, especially one done at the hands of a skilled stylist. "I know it's a cliché to talk about a comb-over," he said, but "there are ways in which you can leave a little bit of hair and not have it be very obvious." He recommends a comb-over to some clients who are losing a significant amount of hair on the crown of their head. But maintaining a chic comb-over requires more frequent visits to the salon, to make sure the combing isn't too obvious. A man with thinning hair who chooses to rock a comb-over might need to visit their stylist every four to six weeks to ensure the remaining hair remains neat and not overgrown. Small also recommends using a powdered dry shampoo to minimize greasiness, which can make hair lie flat on the scalp. Keeping hair dry can add volume, making your hair look fuller. He says look for a dry shampoo that is not aerosolized — those spray cans can be loaded with up to 95% propellants like benzene, which isn't actually helping absorb any oil; it's just pushing the spray out of the can. Also avoid dry shampoos with alcohol in them, which can dry out your scalp. Instead, find a small bottle of dry shampoo powder, ideally one where 100% of the ingredients target oil absorption. Consider changing your part or chopping off some length to help your hair look fuller If you're noticing a visible bald spot on your head, you might want to change up your part so more hair covers the exposed thinning area, Small said. Though the change might feel "awkward" at first, the stylist recommends trying out a new part with wet hair and blow-drying your hair in the direction of the part. Changing your part later on, once hair is dry, might make the hair "stick up" unnaturally, Small said. If you happen to have a longer hairstyle, chopping off some of that length can also help make hair look fuller. "The longer your hair is, the finer your hair will look," he said. Finally, don't let your hair loss deter you from keeping your scalp healthy and clean. If you wash your hair frequently, find a gentle shampoo that won't over-cleanse. You may also want to consider a weekly scrub, like an acid-based exfoliating treatment that can help "balance the bacteria" on your scalp, Small said. Above all, be open with your hair stylist Small says he understands it can be hard for clients to bring up new hair loss issues with their stylist. "A lot of times people aren't really willing to talk about it," he said. He tries to find "tasteful" ways to broach issues or changes he's seeing on a particular client's scalp. "Our job is to have a conversation that a wife or a friend might not have," he said. from Business Insider
Breakthrough Hair Loss Treatment May Have Been Discovered Using MicroRNA
Male pattern baldness, a type of hereditary hair loss, is very common among men. In fact, about two-thirds of men will experience an appreciable amount of hair loss by the time they reach age 35. And, by the age of 50, this figure rises to 85%. Additionally, a quarter of men will begin to have hair loss even before they are 21. Hair loss can be troubling for menTrusted Source with many reporting that their baldness makes them feel less attractive, depressed, or fearful of growing older. Now, however, researchers say they may have found a promising new treatment for this often emotionally distressing condition. According to the study authors, hair follicles become stiffer due to aging. However, their study, which appears in the journal PNAS, found that softening hair follicle cells by increasing the production of a particular type of microRNA could aid in increasing hair growth and regeneration. Tiny RNA particles may be the key to reversing baldness According to board-certified cosmetic dermatologist Dr. Michele Green, who was not involved in the study, hair follicles have various stem cells that are responsible for the regulation of hair growth. “This new study may have found a breakthrough in hair regeneration using small RNA particles or microRNA,” she explained. “More specifically,” she noted, “miR-205 has been identified as an important microRNA that can potentially stimulate hair growth.” Green said that RNA (ribonucleic acid) is present in all living cells. It acts as a messenger to carry instructions from our DNA to regulate protein production. Hair follicles can become stiffer as we age, which, in turn, affects hair growth. “In this study, researchers found that increasing the production of miR-205 softened the stem cells,” said Green. “By softening the hair follicle stem cells, hair growth increased in both young and old mice.” The effect was fairly quick, as well. Green noted that there was increased hair growth after just ten days. How this would be different from current baldness treatments Dr. Ken L. Williams, Jr., a hair surgeon and founder of Orange County Hair Restoration in Irvine, CA, who was also not a part of the study, explained that current FDA-approved treatments for hair loss and thinning in both men and women include:
“Hair restoration surgery is also a successful surgical decision for patients who meet criteria,” he added. Green further explained that any treatment based on the current study would work via a different mechanism than what we currently have available. “Minoxidil works by shortening the resting phase of the hair growth cycle and elongating the growth phase,” she said. “Minoxidil also reverses follicle miniaturization and stimulates circulation around the hair follicles.” In the case of finasteride, it works by inhibiting DHT, which is a male hormone that is responsible for male pattern baldness. “Hair follicles are sensitive to hormonal changes and especially DHT,” she added. Laser light therapyTrusted Source utilizes light in wavelengths ranging from red to infrared to stimulate tissue regeneration and repair. Finally, she said, PRP involves injecting a concentration of platelets rich in growth factors, which improves the health of follicles, increases blood supply, and stimulates reparative cells. What this could mean for the future of hair loss treatment Williams said, “The final outcomes or medical translation of these types of data is always promising, but is impossible to determine so early after discovery.” However, he noted that it is possible that a new treatment will be developed based on these findings. Green additionally cautioned that the study was only performed on genetically engineered mice. More research is needed before we will know if this process will work in humans, she advised. However, if a new treatment does come to fruition, it will “significantly advance hair restoration,” Green concluded, noting that she believes that researchers will probably look at a topical treatment that delivers microRNA directly into the skin. Williams said, however, that it is too early to know what type of delivery system will be created for miR-205, whether that would be a transdermal injection or an oral tablet. from Healthline
Summary: In a new study, researchers discovered that age-related stiffness in hair follicle stem cells can inhibit hair growth. By enhancing the production of a tiny RNA, miR-205, they managed to soften these cells, encouraging hair growth in both young and old mice. These findings indicate the potential for stimulating hair growth by manipulating cell mechanics. This could pave the way for novel treatments for hair loss, with future tests set to determine whether topically delivered miR-205 can stimulate hair growth in humans. Key Facts:
Source: Northwestern University Coaxing hair growth in aging hair follicle stem cells Softening stiff hair follicle stem cells with a microRNA regrows hair Just as people’s joints can get stiff as they age and make it harder for them to move around, hair follicle stem cells also get stiff, making it harder for them to grow hair, reports a new Northwestern Medicine study. But if the hair follicle’s stem cells are softened, they are more likely to produce hair, the scientists found. Northwestern scientists discovered how to soften up those stem cells to enable them to grow hair again. In a study in mice published this week in PNAS, the investigators report that they can soften the stem cells by boosting the production of a tiny RNA, miR-205, that relaxes the hardness of the cells. When scientists genetically manipulated the stem cells to produce more miR-205, it promoted hair growth in young and old mice. “They started to grow hair in 10 days,” said corresponding author Rui Yi, the Paul E. Steiner Research Professor of Pathology and professor of dermatology at Northwestern University Feinberg School of Medicine. “These are not new stem cells being generated. We are stimulating the existing stem cells to grow hair. A lot of times we still have stem cells, but they may not be able to generate the hair. “Our study demonstrates the possibility of stimulating hair growth by regulating cell mechanics. Because of the potential to deliver microRNA by nanoparticles directly into the skin, next we will test whether topically delivered miR-205 can stimulate hair growth first in mice. If successful, we will design experiments to test whether this microRNA can promote hair growth potentially in humans.” This study was conducted in genetically engineered mouse models. The scientists used advanced microscopy tools, including atomic force microscopy, to measure the stiffness and two-photon microscopy to monitor cell behaviors in live animals. The article is titled “MicroRNA-205 promotes hair regeneration by modulating mechanical properties of hair follicle stem cells.” Other Northwestern authors include Jingjing Wang, Yuheng Fu and Kathleen Green.

PNAS Abstract MicroRNA-205 promotes hair regeneration by modulating mechanical properties of hair follicle stem cells Stiffness and actomyosin contractility are intrinsic mechanical properties of animal cells required for the shaping of tissues. However, whether tissue stem cells (SCs) and progenitors located within SC niche have different mechanical properties that modulate their size and function remains unclear. Here, we show that hair follicle SCs in the bulge are stiff with high actomyosin contractility and resistant to size change, whereas hair germ (HG) progenitors are soft and periodically enlarge and contract during quiescence. During activation of hair follicle growth, HGs reduce contraction and more frequently enlarge, a process that is associated with weakening of the actomyosin network, nuclear YAP accumulation, and cell cycle reentry. Induction of miR-205, a novel regulator of the actomyosin cytoskeleton, reduces actomyosin contractility and activates hair regeneration in young and old mice. This study reveals the control of tissue SC size and activities by spatiotemporally compartmentalized mechanical properties and demonstrates the possibility to stimulate tissue regeneration by fine-tuning cell mechanics. |
