Last Updated on September 6, 2023 by Chase Reiner

Hair typically grows about 0.5 inches (1.27 cm) per month, so after one year of shaving, you can expect approximately 6 inches (15.24 cm) of hair growth. However, individual growth rates may vary.

Chart For Different Age-Wise Growth

We have put together this helpful table to understand this hair subject better. It shows you how long hair can grow throughout a person’s lifetime. We assumed they would never shave their hair until they got to forty. 

AgeHair Length
Infant (6 months) 0.25 inches
Toddler (2.5 years)4.25 inches
School-going Kid (6 years)3 inches
Teenager (15 years)7.5 inches
Young Adult (25 years)12.5 inches
Middle-Age Man (40 years)20 inches

As you can see, you’re looking at a 20-inch hair length for anyone who won’t shave until 40 years. That’s true, especially if you look at the Rastafarian community, for example, and its age-old culture of keeping long hair.

Now, let me explain the factors that influence hair growth and increase follicle development using excellent natural methods.

Factors That Affect The Rate Of Hair Growth

Factors That Affect The Rate Of Hair Growth


Hair grows faster in warmer temperatures. However, the sun can cause harm to the scalp and hair. In such conditions, you can shield your hair from the sun’s rays using a hat, a towel, or sunscreen. A cold temperature might also have an impact on hair development. Cold air may cause hair to become dry, fragile, and brittle.

Rest And Sleep

Adequate rest is essential for the body and our hair. Sleep deprivation may have a deleterious impact on various biological functions, including hair growth. Make it a point to rest when tired, and aim for at least 7 hours of sleep every day.


It is essential for maintaining healthy skin and hair. Your hair growth, strength, and volume can be influenced by the foods you eat. Fresh fruits and vegetables can be included in your diet to stimulate faster hair development. Good nutrition means you’re in an ideal shape to grow solid and lustrous locks.

Vitamins And Minerals

The finest source of vitamins for hair development is food. Vitamin B is very beneficial for healthy hair development. Iron, zinc, iodine, and silica are all essential minerals. However, overuse of either can be dangerous. It would help if you always spoke with a doctor before using them to decide which vitamins and minerals are best for you.


This is the primary point of the article. Hair development in both males and females often corresponds with chronological age. Therefore, the older you become, the more likely your hair will grow slowly. The following section discusses hair development by age group.


When newborns are born, they either have no hair or have enough hair to cover their heads. They will, however, lose all of their hair throughout the first six months of their life as they mature. After that, the hair can re-grow, but it will have a different texture and color than before.

However, there is no scientific proof that cutting a child’s hair causes it to grow quickly. When you trim and clean up the rough ends of their hair and shape and style it, you make it look thicker, and, as a result, you notice the growth more. Some children’s hair may come back fast after a clean shave, while others can take several months.


It’s a whole different story for adults. Given that hair grows at a rate of 1-2 inches each month. So, if you follow all of the recommendations, you should be able to accomplish an astounding 3 inches every month, or 10-12inches per year. However, hair growth varies from person to person and is affected by factors such as climate.

Furthermore, hair grows endlessly. It would be difficult to track for a year. Hair grows in varying amounts and at varied rates in different regions of the body. The scalp hair, for example, grows one-half inch every month.

And if certain factors favor you, then you are aiming for the height of 12 inches growth. But as you struggle to grow your hair after a clean shave. Your hair takes turns in several phases to grow -adding inches,  pausing in the resting stage, and making room for new hair growth by entering the shedding phase. This whole cycle is as unique as you are; there’s no one-size-fits-all answer. 

Ethnicity may also play a role, with Asian hair growth demonstrating faster hair growth. Furthermore, different environments will factor in the growth rate. For example, if you spend time in a stressful environment within that year, your hair growth may come to a standstill. 

It might take up to six months for your hair to grow back to its regular rate. However, if the follicular unit is injured or hormonally disrupted, hair may not develop at all. This means that no new hair will grow in the region. As a result, shaving your hair does nothing to encourage hair growth.

And if you cut your hair near the scalp, it will only be visible to you if it is growing. Having that at the back of your mind, you should know that the follicular unit doesn’t understand a thing about hair. So even when you pluck it away, the follicular unit just continues to grow.

Ways To Speed Up Hair Growth

Ways To Speed Up Hair Growth

After shaving your hair and attempting to re-grow it, the procedure might take an eternity. Therefore, here are some ideas for quickening the process.

1. Add Proteins And Vitamins To Your Diet

You can consume foods like milk, cheese, spinach, yogurt, eggs, parsley, cabbage, and avocado. They have zinc and selenium, which are essential vitamins for healthy hair.

2. Massage Your Hair With Hot Oils.

Massage sweet almond oil, castor oil, and coconut oil into your hair. The massage stimulates blood circulation in your scalp, resulting in the development of new hair follicles. You can add oils like lavender, rosemary oil, or thyme oil to the hot mixture if you like.

3. Rub Your Scalp With Coconut Milk.

Coconut milk is high in vitamins B, C, and E and calcium, magnesium, iron, phosphorus, selenium, and a variety of other minerals. It nourishes your hair, encourages development, and protects against hair loss. Repeat this process two to four times each month.

4. Avoid Stressful Environments.

Stressful environments can alter the hair cycle, preventing it from growing quickly. The greatest approach to calming oneself is to alleviate stress through meditation, yoga, or other breathing techniques.

5. Apply Lemon Juice To Your Scalp

They are high in vitamin C, B1, B2, B3, B5, B6, B12, folic acid, and other minerals. This nutrient encourages hair development, leaving it smooth, lustrous, and dandruff-free. Simply combine it with olive oil or coconut oil. Apply the mixture to your scalp twice a week for best results.

The pace at which your hair grows can be determined by factors such as pre-shave growth rate, environment, nutrition, age, and other factors. Unfortunately, you can’t tell how long it’ll take you to grow your hair back after shaving it. It all depends on your particular habits, lifestyle, and diet, which is the final but not least aspect influencing your hair development.

You may have some hair loss along the process. This is a frustrating issue, and there may be nothing you can do about it. And genetics and age will be the most critical factors in your hair loss. If your hair loss has become a nuisance, the best thing to do is consult with your doctor. They may be able to determine the reason for your hair loss and provide a treatment strategy based on your specific situation.

Does shaving make hair grow faster or thicker?

This question has been a subject of pondering for many and it’s time to break down the myths and facts about this topic. Here is a listicle diving into whether or not shaving makes hair grow faster or thicker.

1. The Origin of the Myth:

The belief that shaving could prompt hair to regrow faster and thicker dates back to centuries. Men in their adolescent years usually start noticing hair growing more rapidly and denser when they begin to shave. This correlation often gives birth to the misconception.

2. Association with Age and Genetics:

Hair growth is more affiliated with genetic and hormonal factors rather than external factors like shaving. As young men hit puberty, the transformation of vellus hair into terminal hair, often experienced as increased hair growth, is in fact a marker of maturing rather than the effect of shaving.

3. The Scientific Perspective:

According to a scientific study from the Mayo Clinic, shaving doesn’t affect the density or speed of hair growth. Hair follicles are situated underneath the skin surface, hence the act of shaving, which only cuts hair on the surface, does not influence its growth pace or thickness.

4. The Tricky Perception:

While it may seem like the hair is growing thicker after shaving, this is a deceptive perception. What actually happens is that the razor shears off the hair tips, leaving behind a sharp-edged stubble when it starts growing back. This imparts a feeling of coarseness and thickness which is often mistaken for increased hair growth.

5. The Role of Shaving:

Shaving does not interfere with the physiological process of hair growth. The hair shaft thickens as it matures under the influence of hormones but shaving has no role to play in it.

In conclusion, it’s imperative to understand the science behind body processes before binding to popular beliefs. The fact remains that shaving does not make hair grow faster or thicker, it’s simply a perception due to the manner of regrowth post-shave. Remember, it’s important to shave safely and take good care of your skin regardless.
