If you have ever wondered whether greying hair and losing hair are related, the short answer is yes, they are. A cancer researcher in Texas has discovered by accident that, in fact, they are closely related, in mice at least.
While studying tumor growth and development, Dr. Lu Le found that a protein called KROX20 not only affects tumor growth but also turns on and off skin cells that form hair shafts. When these skin cells turn into hair shafts, the cells produce another protein called SCF or Stem Cell Factor, which is necessary for hair color.
When scientists deleted the KROX20 protein cells, the mice didn’t have any skin cells turns into hair shafts, and their hair all fell out. When the scientists deleted the SCF protein cells from the skin cells, the mice couldn’t form color in their hair cells, so all their hair turned grey and then white.
So what does it all mean?
This is an interesting discovery. KROX20 and SCF are not the only reasons that hair falls out or turns grey/white, but they are definitely one of the reasons.
Hair loss in your 30s, 40s, 50s and beyond is highly common. Many adults expect some thinning and shedding to occur with age, although individual cases largely depend on genetics, hormones, and lifestyle. However, some people experience hair loss much earlier on in life – even during those critical teenage years when self-perception and scrutiny are at all-time highs. More than the emotional impact, hair loss at an early age might be a warning sign of something more serious, such as an undiagnosed illness.
Hair loss is a natural process. In fact, the average human being loses anywhere between 50 and 100 strands a day. Since hair is constantly undergoing regrowth, strands seen in the shower drain or in the teeth of your hair brush may be completely normal, and could actually indicate you're about to experience fuller hair. However, when you start to see excessive shedding that is visually apparent on your scalp, it’s time to take action. Consider the following six factors that can contribute to hair loss unrelated to genetics or medical conditions.
Men and women often wonder how to stop hair fall. Excessive thinning and shedding—often perceived as “hair fall”—can be just as worrisome as pattern baldness. For many, the ideaof losing hair can be just as harmful to confidence and self esteem as full blown androgenetic alopecia. In this article, we examine the characteristics of excessive hair fall and the treatments that are available to stop the progression of hair loss while creating conditions for thicker and fuller looking hair.
When it comes to treating hair loss, there is no shortage of companies claiming to have the secret to fuller and thicker looking hair. From vitamin supplements to messy topical foams, pharmacies and websites are well stocked with products that often times over-promise and under-deliver. According to Capillus physician, Dr. Yates, hair loss sufferers are wise to choose a treatment that is backed by scientific research. Those options include Rogaine®, Propecia®, PRP and low level laser therapy. "If you turn on the TV or look in a magazine, there are a bazillion products out there that will supposedly grow your hair," Dr. Yates states in an interview published by Business Insider. "But the fact remains those are probably the only four things that I know of that have some scientific basis." One thing each of these hair loss treatments has in common is a focus on the hair follicle. Whereas keratin shampoos and hair growth supplements are marketed as “nourishing” to the hair itself, these 4 treatment options focus on helping hair follicles support a natural growth cycle. That’s a better approach, since hair cannot grow if a follicle becomes damaged, goes dormant, or otherwise stops producing hair. When choosing among the 4 options listed by Dr. Yates, many patients find laser therapy to be the most convenient. Whereas Rogaine® foam requires twice daily application (directly to the scalp) and Propecia® has been outted for long term sexual side effects among some of the men who take it, laser therapy provides a simpler solution that is safe, proven, and effective. In clinical trials, patients using Capillus® laser technology saw a 51% increase in hair count, without tedious Rogaine® applications or the risk of side effects (source: ClinicalTrials.gov).
