How Long Does It Take For Hair To Grow Back?

How Long Does It Take For Hair To Grow Back?

After a haircut, and especially if you had a bad haircut, you may be wondering how long does it take for hair to grow back?

For different reasons you may want to know how quickly you can regain the length of your hair. A bad haircut, damage at the ends chemical damage such as straightening or bleaching are some examples.

The average time it takes for the hair to grow back is 1 cm per month. If you need it to grow 6 cm approximately 6 months will take to get it. For some people depending on genetics hair grow slower or even slightly faster. This process can be accelerated using products that contain biotin, collagen, other amino acids, and nutrients.

There are other ways to help you grow hair faster, some are natural and others are superficial, such as extensions or wigs.

Depending on the goal you want to achieve, you can rest assured that there is a solution. Here I will talk about the most effective solutions for this problem.

How Long Does It Take For Hair To Grow Back Again?

Hair takes typically 4 weeks to see a change in your hair length. Every month the hair grows 1 cm on average. That means that 0.033 mm is what grows every day.

If you have recently cut your hair or experienced any damage. The centimeters that you have cut or have been damaged, will be the time it will take to grow back. Proportionately 1 cm per month.

Genetics always influences that some people have slightly less growth and others are the exception, growing more than that per month. However, most people have confirmed that 1 cm is what they grow.

There are two important things that you must differentiate:

  • Hair loss
  • The hair growth cycle

You have to know that they are two separate things. An example is that if you see that the hair grows its length, it does not mean that it will not fall. Likewise, if you have hair loss, it has nothing to do with your hair continuing to grow.

Each hair strand is independent, they can be in a different stage of the growth cycle, and do not affect each other.

Understanding How Long It Takes For Hair To Grow Back

Another very important thing to know is when the damage at the ends is irreparable like when they are completely open like tree split ends, or shrunk by chemicals. It is better to cut them because they will not be able to repair themselves and then you will not be able to see the growth you are looking for. The correct thing to do is to cut the damaged part and then follow the advice that I will give you below to accelerate growth.

I will focus on how hair grows, its cycle, and two very important aspects:

  1. How Is The Hair Growth Cycle?
  2. How can you help it to grow faster?
  3. How to keep the hair growing

With this, you will solve your doubt with solutions to recover your hair and your peace of mind.

#1 How Is The Hair Growth Cycle?

The hair has a cycle that has 4 phases. The first is called Anagen and is where the hair is growing. This phase lasts from 5 to 9 years. 90 percent of the hair is most of the time in the growth phase.

In the following stages of Catagen and Telogen, the hair separates from the follicle and rests for about 3 months before it falls off. This last happened in the last phase called Exogen. A day between 50 and 100 hairs is within the normal range that can fall out.

All this means that most hair spends more time in the growth phase than we think. That’s where we can help you increase that length and see it reflected faster.

Also, the breakage of the ends affects the length of the hair since it breaks before reaching its maximum length. Unlike hair loss where the hair is already on the head and cannot return to the head. Split ends can be healed and treated in order to get them back.

After you cut your hair the hair growth process doesn’t stop but just stays the same. The only thing that happens is that what you have cut will have to grow again. If you have cut 3 fingers long what you should wait in a standard time would be 3 months.

#2 How can My Hair grow faster?

How can Hair grow faster

As we saw in the hair growth stage, is where we can add specific nutrients to motivate and accelerate that growth. To make it grow faster, adding to your routine specific ingredients in the form that the hair needs will shorten that time, such as:

  • Biotin
  • Zinc
  • Collagen
  • Niacin
  • Iron
  • Amino’s

When we increase the production of these ingredients you will be able to see that the hair after a time of use grows more. So you can see it longer in less time. I recommend those ingredients be applied directly to the hair and not taken by pills or supplements. This is because the metabolic process of doing it this way takes longer and is difficult to know where the body is going to put those ingredients. When you apply it directly you make sure that the hair absorbs the benefits immediately thanks to the technology of the products.

A product that for me is one of the best to really make your hair grow faster is this line of shampoo, conditioner, and serum. With them, you can see real results of faster growth. In 3 months you can see a significant thickening up to 5 cm in length.

You must be very constantly applying your products every 3 days and at least once a week. Remember that you must let your hair dry for 24 hours before washing again so as not to erode the fiber and keep it healthy. The serum can be applied every day to strengthen the tips.

#3 How Can I Keep My Hair Growing?

To enjoy long hair for longer, you have to strengthen the ends because it is the area furthest from where the hair receives the nutrient. When the ends are malnourished, weak, or dry, they break and you will never see the length.

To strengthen dry and damaged ends, it is good that you regularly apply an end-sealing serum. If it is due to damage, use Therapiste serum, which is the strongest and most restorative that I have seen and in a few weeks you will find the strongest ends, so that the hair can continue to grow without breaking and look healthy and strong.

Apply one push every day only on the ends. You will feel an immediate softness and a very pleasant smell. If you apply it more times a day, it will be much stronger in less time.



You already know the key points of the hair growth cycle and how long it takes for the hair to grow back. In order to help you speed up the time your hair grows or simply improve your appearance, you can use special products to solve your problem. Remember that you must constantly apply them regularly and as the instructions tell you

I hope it has been helpful to you.
