Cutting split ends on regular basis may not help. It may damage your hair growth.
Yes, I think that cutting split ends can help with hair growth. There are many other ways for increasing the hair growth. Consuming collagen or gelatin also increases hair growth naturally. Coconut oil and coconut milk can also promote hair growth. I also read on the internet about hair beauty supply online products. The store has a wide range of hair care products. I read in a magazine that lemons are rich in vitamin C, folic acid, and other nutrients. In addition to hair growth, the lemon juice promotes smooth, shiny, dandruff-free hair.
I heard really a lot of positive reviews on coconut oil and it's beneficial properties, I will definitely check your products, thanks. As for the anti-dandruff effect, it isn't always caused by cosmetics, but such diseases like mallasezia and wide spectrum of infections. Here is a detailed guide how to get rid of this problem http://ohealthyeah.com/dandruff/ , it is easier than it might seem.
Best Wahl Professional Hair Clippers are available for all kinds of uses and you can easily find one that is suitable for your specific needs.
Cutting split ends is just a temporary decision of the problem! Use moisturizing sulfate-free shampoos and conditioners. You also must make sure that your hair straightener or blowdryer doesn't overheat your hair. I read about an appropriate tool for my wavy hair here. Overheating hair with a flat iron can damage it badly. Use care products which do not contain alcohol to reduce the risk of split ends. Coconut oil is good for it too.
Yes, of course, it helps a lot in growing hair. You should get trimmed your hair every 3-4 months. This way your split-ends won't create a problem in your hair growth.
