Well, there is nothing scientific behind this theory. Hair grows from the root, and cutting the ends has no impact on the speed of growth. What does affect growth is the health of your scalp and things like nutrition, circulation, and overall health. The healthier you are, the better your hair will grow. Now don’t take this to mean you shouldn’t cut your hair. Regular trims will keep your ends in better shape, reducing the occurrence of slit ends, and the disintegration effect of hair ends. It seems to reason that the idea behind cutting makes hair grow faster has to do with the fact that healthier ends don’t break off, shortening the strand. When happy ends stay intact, you may feel like you are gaining length faster. That’s just my thoughts on the matter though, I can’t say it is a scientific theory by any stretch.
Washing your hair in cold water makes it shinier.
The truth of the matter is, water temperature really doesn’t have any effect on the reflective quality of hair. Shine on hair is dulled by damage and product build up. If the cuticle is damaged, the shine goes away. Just like a foggy or dirty mirror doesn’t reflect and calcium on windows make them less see through. If residues are on the hair strand, the reflective quality will be diminished. Water chemistry can affect your hair strands. High ph is known to swell cuticle scales open, while lower ph will cause them to lay flatter. This has an effect on how smooth or tangly your hair is more so than the shine. Conditioners are what help with shine. So the good news is, you don’t have to keep taking those cold showers. Now that's a relief, isn't it?
Split ends can be repaired.
This is also not true. The appearance of split ends can be reduced and hidden, but repairs or healing aren’t possible on hair strands. Once the damage is there, the damage is there until it is cut off.
There definitely are products that will improve the appearance of split ends, and can even close them up, but without continued use of the product, the repair is temporary, just like any thing else done to the hair strand. The best cure for split ends is prevention and proper maintenance. like regular trims, proper care, quality products, and lower heat during styling.
There is one product that I know of that is using ionic attraction to create a repair effect and it is permanent with continued use. Monat's Rejuvabeads is a patent pending and award winning new product that does an amazing job of restoring hair with split ends. Testing has shown a 100% closure rate on splits 3mm or less (that's huge in hair terms.). It will even restore micro damage on the strand caused by rough handling and over-styling. That is a very cool thing!
Air drying is always better than blow drying.
While this makes sense in theory, it isn’t entirely true. The importance is in how quickly water is removed from hair. Water on the hair strand is prone to soaking in, which causes swelling inside the hair, which can cause cuticle damage.
Healthy hair is water tight. Water beads up off it like it does on a freshly waxed car. Damaged hair, processed hair, dry, tired, stressed hair has lost its seal, and acts like a sponge. The more porous or spongelike hair is, the faster it absorbs water. This is why getting hair dry faster is always better. A dryer on a cooler setting is preferable on longer hair. Short hair that dries quickly is not as impacted by air drying. It seems like water would be a great moisturizer, but it actually can affect keratin and make hair more brittle and dry. Crazy, huh?
Marsha from the Brady Bunch had great hair because she brushed it, and you should too.
The opposite is actually true. Brushing hair doesn’t improve shine, or strength. Hair isn’t like a muscle that improves with working it out. Hair only degrades. The more you manipulate it, the more you do to it, the faster it will degrade. Just like that favorite shirt or pair of jeans, the more you wear and do to them, the faster they fade and begin to fall apart.
It is important to comb or brush to detangle hair, and it is important to do it gently. Brushing hair creates friction and stress on the strand. The harder and more frequent you brush, the more the physical forces accumulate and effect the strand. Many of your favorite hair products talk about testing ingredients that reduce the stress and friction of combing and brushing for this very reason. I know, you are thinking, “well, all these hair blogs talk about the benefit of brushing your hair and scalp with a boar bristle brush”. True, they do, are they science based or commerce based blogs though? Are the authors researchers or are they lay people?
I’m also not a big proponent of scalp brushing, I will recommend it to some experiencing excessive flaking, but prefer scalp manipulation with fingertips over brush bristles to stimulate and increase circulation. Aggressive brushing of the scalp can irritate and abrade the tissues of the scalp causing inflammation and possibly other adverse reactions.
Hair gets used to shampoo and that shampoo will stop working.
Nothing can be farther from the truth. Again, since hair is not viable, it can not build up a tolerance or an addiction to products. What can happen is the chosen product is designed for a very narrow result such as, hydrating dry strands, and may contain ingredients that seal that moisture in. 2 things may occur that lead you to think the product is no longer effective. 1. The hydration level has been reached, and 2. the sealing ingredients have created a build up that make hair heavy, dull, or even begin to dry it out. It isn’t the hair, it is the ingredients in the product. This is why gentle yet effective cleansers are essential in cleansers, and rotating in a clarifying shampoo once every 7-ish washes is a good addition.
When choosing product, choose one that suites your hair type and hair goals. If you have fine hair that falls flat easily, and you wish for big, voluminous, bombshell tresses, a quality volumizing line that uses high grade ingredients is your best friend. I have clients that have been using my Monat product recommendations for 3 years and longer with no change in the efficacy or results. When the product is matched to your hair type, you can use it indefinitely, or until your desired results change.
We all read the instructions on the back of the bottle and have thought the lather and repeat point was to just get us to use the product up faster, right?
This is one I used to think was true myself. As my education and understanding increased during my career, I learned otherwise.
2 lathers are better regarding cleansing, will give better sudsing action, and can help you use less product over all.
The first lather can be thought of as similar to priming your walls for paint. When you prime a wall, you use less paint, right? Since dirty hair doesn’t lather well, the more styling product on the strands, the more this is true. It would take more shampoo to build a good head of lather. When you use a small portion as a priming wash, the second lather takes a smaller amount as well. For instance, if you need a palm full of shampoo to make a great lather, you can use a nickel to quarter size portion on later 1, and then a quarter size portion on the second lather and get copious suds on lather 2. Over all, you have used less product on 2 lathers than that single lather you are used to.
The first lather begins lifting residue and grime from the stands, and the 2nd lather pulls the product fragments and molecules together to move them off your hair and down the drain, resulting in a better clean. This is especially true when using milder cleansing formulations that are less abrasive on your hair strands.
When considering chemical treatments for your hair, the second lather is essential to remove the last bits of active peroxides on the hair strands. Peroxides are oxidants that will cause dryness, color fading, and weak spots in the hair if left on the strands. The second lather after processing your strands rids your strands of those little culprits.
A point about lather:It doesn’t take suds to cleanse your hair, scalp or skin. We enjoy lather, and equate more lather to better cleansing, but there isn’t a true correlation there. What suds do is help move ingredients through the strands and make it easier to cover all hairs with product. When using a line with beneficial ingredients, suds can help disperse the good stuff more quickly and uniformly.
