This is one of those myths that refuse to die. Regardless where you go, either salons or hair forums, you will always find at least one person that bleats the fact that trimming your hair makes it grow faster. But how much truth is there to the theory?
To tackle this theory we will first have to identify a few facts about hair and about hair growth:
Fact one: Hair structure – The hair cuticle has many layers and as the hair grows each of these layers is stripped away due to many things such as wetting, heat styling, stretching, braiding, roller setting, combing, brushing and many other factors that are too many to name here.
The structure of the hair is important because you will notice that the ends of the hair are typically much thinner at the ends in comparison to the root.
Fact two: Trimming split ends will help to make the hair healthier. Split ends travel; they start in one area usually at the end of the hair and literally will split further up the hair shaft, often damaging perfectly healthy areas of the hair strand.
Contrary to popular belief however, splits are unlikely to split all the way to the root of your hair! But they can definitely travel a good few inches.
Fact three: We have all heard that maintaining a healthy diet and lifestyle is the secret to avid growth but in addition to these facts genetics plays a large role as well in how long your hair will eventually get.
Each of us has a specific code that determines hair thickness, length, texture and all the things that make us and our hair so very special.
Fact Four: Hair growth is cyclical and has three specific concurrent phases, these are anagen, catagen and telogen phase. Each of the phases has its own unique characteristics that determine hair length.
Another great fact is that not all of your hair is at the same stage at any one time, so when one strand may be at telogen another maybe just at anagen! Pretty cool huh?
