Does trimming hair help growth?

Trimming Hair for Hair Growth

No, trimming your hair often to promote hair growth is a myth. Your hair growth is based solely on hair follicles in your scalp which determine how your hair grows. Therefore, cutting the ends doesn't affect the follicles which are located in your scalp.

The myth is due to a perceived increase in hair growth after cutting and from the reduced hair breakage after your trim the ends.

Excessive Hair Shedding Vs Hair Loss

Firstly from America Academy of Dermatology, you need to understand the differences between hair shedding and hair loss. Hair shedding is just the normal process of losing hair. Excessive hair shedding is the condition telogen effluvium whereby you lose more than 50-100 hair a day. Hair shedding usually recovers on its own and happened due to a stressful or life-changing event such as becoming a new mom, relationship issues, career changes, business struggles, or health issues. 

Unlike excessive hair shedding, hair loss is the condition anagen effluvium whereby the hair stops growing. This is the problem most people seek professional help from as it cannot be resolved on its own.

Understanding Hair Follicle

Our hair follicle resides in the dermal layer of the skin and is made up of 20 different cell types, each with distinct functions.

Hair growth is determined via the reactions between hormones, neuropeptides, and immune cells.

These reactions affect different types of hair on our body, including eyebrows, armpit and of course hair on our head. 

Hair growth happens in the following stages:

1. Anagen (Growing Phase): The anagen, or growing, phase usually lasts 2-7 years, and the length of this phase determines the length of our hair.

2. Catagen (Transition Phase): This is the transitional phase that lasts about ten days. During this stage, the hair follicle decreases in size and detaches from the dermal papilla.

3. Telogen (Resting Phase): This is the telogen, or resting, phase, which generally lasts around 3 months. Around 10-15% of the hair on your head is in this phase at any given time. While the old hair is resting, a new hair begins the growing phase.

4. Exogen (Shedding Phase): This is a part of the resting phase where the old hair detaches and sheds, and new hair continues to grow. Approximately 50 to 150 of your hairs may fall out daily. That is considered a normal rate of hair shedding.

Understanding Hair Growth

Hair grows an average of a quarter-inch every month whether you trim it often. Regular trims get rid of split ends and reduce hair breakage. The breakage makes hair look thinner at the ends and shorter.
