Sheep wool provides clues
There has been no research that explains what gives the curl to curly hair. To understand this, the researchers looked at the microscopic structure of the hair and measure the individual hair cells in the curly hair that could explain the curls. However human hair was found to be too thick for these experiments. So as a next step they looked at naturally curly hair or wool from six Merino sheep from New Zealand. This provided them with the answers they were looking for. The study results were published this week in the latest issue of the Journal of Experimental Biology. The key finding from the experiment was that in hair that was curly, the cells that are outside the curls are longer than those that are inside. In straighter hair the cells in both outer and inner sides were similar in length. This has been seen at least in the sheep’s wool say experts and they believe that similar findings may be expected in humans. The cell length inside and outside of the hair bends thus determine the curliness of the hair. This, say researchers, could pave way for new hair care and styling products that could provide longer lasting curls or straightened hair. Cosmetics company, Kao Corporation from Japan, part funded this study. Study’s lead author Duane Harland from AgResearch in New Zealand said that the reason why they chose sheep’s wool is because merino sheep wool is around five times finer than human hair but they have a similar biology. Thus this wool could act as a reliable hair model. Dr Harland said these fibres are of different sizes but are still relevant to human hair and additionally microscopes can penetrate more easily through the finer fibres of the hair to see the individual hair cells and gauge their differences. He explained that in order to understand and count the cells there has to be thin layers and minimal cells. Also the merino wool has no pigments and is transparent. This makes the cells better visible than human hair. He explained that hair is made up of keratin protein. Within the hair there are parallel strands of this protein called the paracortical cells. There are also orthocortical cells that have twisted fibres of keratin protein. These orthocortical cells are outer cells that are longer while the paracortical cells are shorter. This could explain the curliness. The design is similar to an archway he said. For the study the team sheared 6 merino sheep. They had kept the sheep in identical conditions for past 6 months. From the wool they chose 700 fibres for the experiment. Each of these was five micrometres or less in diameter and half a centimetre in length. The washed the fibres to remove the lanolin coating over them and revealed the natural state of the fibres. After drying them over a vibrating surface to prevent adhesion or kinking they were cut and examined under the microscope using electrostatic forces. They cannot be picked up individually said Dr. Harland because that would damage their insides. Now under the microscope they could measure the curvature of the fibres and look at their cell structure. They noted from their observations that the orthocortical cells lay on top of the fibres and were longer than the paracortical cells at specific locations. Where the orthocortical cells were longer, the hair tended to curl. More studies are necessary to understand how these differences in length are important. Genetics of hair curling also needs to be studied he said. This article first appeared on News - Medical - Life Sciences

4/2/2018 Spring Break Hairstyle IdeasThe Best Spring Break Hairstyle Ideas
For those of us living in cold weather climate, spring break is the first hint of warm weather after a long and snow-filled winter. Spending time fussing about your hair while on spring break is a downer—after all there’s some serious beach time to sneak in! Vacation is all about easy and effortless hairstyles. The last thing you want to do is spend extra time in the hotel room trying to perfect your ‘do. Here are some of the cutest spring break hairstyles that don’t require much effort. Messy Topknot We love this look for the beach and apres swimming to tame any frizz and keep hair out of your face. If you haven’t heard, messy is now considered the ultimate in chic. An insouciant look means you didn’t try too hard but still manage to look gorgeous. How to get the Look: Here’s how to nail the perfect messy top knot: Gather all of your hair into a high ponytail on top of your head. Leave out the ends of hair on the last loop of the elastic. Gather all of the loose ends and, using bobby pins sprayed with hairspray, pin them around the bun. Lastly, tug at the bun a bit to create a haphazardly chic look. Heat Free Beach Waves While at the beach, wavy beach hair makes perfect sense. Even if hitting the waves isn’t your thing, rocking waves in your hair is a vacation homerun. The fabulous rule about vacation hair, is that it should look undone and beach waves are ideal iteration of that just-rolled-out-of-bed hairstyle. How to get the look: Head to the beach with slightly damp hair. Spray HSI Argan Oil Leave In Hair Treatment into locks and using your hands, give hair a good scrunch. Twist hair into two braids and hit the beach. Let the sun air-dry hair. Undo braids and voila, beachy waves! The Half-Up Top Knot This is the sister hairstyle to the full on top knot. It’s the ultimate lazy girl hair style, but has a hint of sexiness, too. How to get the look: This time, instead of grabbing all of your hair to put into a top knot, grab only hair from the top half of your head. Follow the same guidelines using an snag-free elastic to twist hair into a messy bun and secure with bobby pins. Half Up Twist There’s something about the half-up hairstyle that screams vacation mode. A half up look is easy to create and also lets most of your hair hang loose without the annoying wisps in your face that can happen while on the beach. This twisty half up hairstyle has a hint of princess to it. How to get the look: Taking about an inch of hair from each side of the head, right above each ear, twist each side until they meet in the back of your head. Secure both twists with a small clip or snag-free elastic. Glamorous Waves When you have 15-minutes in your hotel room to get ready for the night out, creating gorgeous vacation-ready waves is the way to go. How to get the look: Spray a texturizing spray onto damp hair. Divide hair into two parts. Twist one section away from the face with your fingers and blast it with a blow dryer. Repeat on the other side. Try the HSI Dryonizer Lite Lightweight Ceramic Blow Dryer, which is super lightweight and perfect for packing into luggage. This article first appeared on HSI Professional Spring is in the hair. I noticed something trending with women's hair at the beginning of the year, shorter hair. It was a new year and women were ready for a new look. With warmer months ahead, women’s hair continues to trend toward shorter, more playful cuts and styles. I have articles for you on spring break style ideas, haircuts you'll be seeing more this spring, and even a how-to on a “flash” from the past hairstyle. You may have also noticed men are starting to grow out their “barbered” haircuts, think the collar-brushing locks of Robert Redford and Dustin Hoffman in All The Presidents’ Men and Chris Hemsworth in Thor. This Have you wondered why some have curly hair and others of us do not? Turns out the answer might be in the wool of sheep. And what about conditioner? What is it exactly? I stumbled across a great NatGeo video explaining the chemistry of conditioner. Bad hair habits. We all have them. It doesn’t take very long to start a bad one. It takes even longer to unlearn a bad habit. So, it’s understandable that it takes a little effort to start and continue a good new routine. I found a nice article about some of the bad habits you’re doing that are wreaking your hair. Healthy hair is an inside job. Not only is a healthy diet important, but so is a healthy scalp. I have an article for you with the best oils for maintaining a healthy scalp for healthy hair and hair growth. Oh, and this happened... As always, thank you for taking the time to look through this months As the Chair Turns. What's Inside This Month
