How fast does hair really grow?
You’re born with all the hair follicles you’ll ever have. Your head alone has about 100,000 follicles. As you age, some follicles stop producing hair, which is what causes baldness or hair thinning.
In total, the growth cycle for each hair on your scalp can take 2 to 6 years.
Hair growth speed depends on factors like your age, hair type, overall health, and certain medical conditions. Read on to learn what we know about the science behind hair growth and how to use that knowledge for healthier hair.
The stages of hair growth
Hair grows in three stages, and each strand of hair follows its own timeline:
- Anagen. The active growth phase of hair lasts 3–10 years.
- Catagen. The transition phase where hair stops growing lasts 2–3 weeks.
- Telogen. The resting phase where hair falls out lasts 3–4 months.
At any given time, the average scalp has 90 percentTrusted Source of the hair follicles in the anagen phase, about 1 percent in the catagen phase, and about 9 percent in the telogen phase. The last group accounts for the approximately 100 to 150 strands of hair that fall out every day.
Can you increase the anagen phase for hair growth?
How long the anagen phase lasts depends on how long your hair is and if the cells in your follicle base are continuing to multiply and become hair cells.
Hair grows because matrix cells shed some of their structure as they reach the upper follicle. The shed structure combines with keratins to form hair strands that exit your skin’s surface.
Researchers are still looking into what triggers our bodies to switch on the anagen phase, and more studies are needed to know for certain what can be done to promote hair growth.
Still, there are steps you can take that may promote healthy hair during the anagen phase.
How to make your hair grow stronger
Hair is made up of keratin and dead skin cells.
While there’s no direct way to make your hair grow faster overnight, there are steps you can take to keep your hair healthy and long.
1. Keep up with vitamins and nutrients
While many companies promote vitamins or supplements for hair growth, they don’t always directly affect hair length. Your body requires a lot of energy to make your hair grow, so getting too few calories and certain nutrients can affect it.
Generally, it’s best to get your vitamins and nutrients from your diet. Still, you may also look into taking certain supplements — particularly if you have a deficiency.
Below are some of the nutrients commonly touted to promote hair growth and the science behind their efficacy:
| Nutrient | Efficacy | Supporting studies |
|---|---|---|
| Omega-3 and DHA | may work | One studyTrusted Source found that a mackerel oil extract lengthened hair fibers and promoted growth during the anagen phase. It’s important to note that this study was conducted on mice; there is currently no credible research done on humans. |
| Zinc | may only affect those with a zinc deficiency | Zinc deficiencyTrusted Source plays a role in hair loss, with lower levels common in alopecia areata — an autoimmune disorder that causes hair loss. |
| Biotin (vitamin B7) | may only affect those with a biotin deficiency | While biotin is often promoted for hair growth, there’s not enough evidenceTrusted Source to show that it works if you’re not deficient. |
| Vitamin C | unlikely, and only supported by anecdotal evidence | The antioxidant effects of vitamin C may help prevent oxidative stress that can cause hair to gray and thin out. However, there’s no evidence that vitamin C directly influences hair growth. |
| Iron | may only affect those with an iron deficiency | Iron deficiency is commonly linked to hair lossTrusted Source. Common signs to look for are hair thinning or more shedding than normal. |
| Vitamin D | may only affect those with autoimmune hair loss | Studies have found that people with alopecia areata commonly have vitamin D deficiencies, but more research is needed to determine if there is a definitive hair loss link. |
A note on supplements
Talk with your doctor before trying supplements like biotin, keratin, or other nutrients. They may interact with any medications you take and cause unintended side effects.

2. Apply essential oils/carrier oils
Put a few drops of tea tree, rosemary, or lime oil into your shampoo or dilute it with jojoba oil.
In one reviewTrusted Source, researchers found that these three oils can improve scalp health. Still, there is a lack of studies proving that any essential oil will make your hair grow faster.
Another reviewTrusted Source found that the below essential oils may benefit hair loss treatment:
- lavender
- chamomile
- thyme
- peppermint
- garlic extract
Avoid applying essential oils directly to your skin. Instead, dilute them in a carrier oil.
While research suggests there are health benefits, the FDA doesn’t monitor or regulate the purity or quality of essential oils. It’s important to talk with a healthcare professional before you begin using essential oils and be sure to research the quality of a brand’s products. Always do a patch test before trying a new essential oil.
For instance, add a few drops of essential oil into 1 ounce (29.6 mL) of carrier oil. Certain carrier oilsTrusted Source may even help moisturize your hair:

- Topical minoxidil 5 percent (Rogaine). Slows hair loss when used daily for 3 to 6 months.

If you style or apply heat to your hair often, using a protein treatment may help protect it. You can purchase these products online.

Caffeine has been shown to promote hair growthTrusted Source, with women being more sensitive to its hair follicle effects.

What can affect hair growth?
Many factors can affect hair growth, including:
- genetics or family history of hair loss
- hormonal changes
- lack of adequate nutrition
- certain medications including chemotherapy
- stress
- recent weight loss of 20 pounds (9 kg) or more
- trauma that damages follicles
- certain diseases or conditions
Hair growth during and after pregnancy
Women who are pregnant may feel that their hair is growing faster. Meanwhile, those who have just had a baby may feel like they’re losing hair faster than normal.
During pregnancy, the hormone estrogen causes you to have a higher ratio of hair follicles in the growing phase. After the baby is born, hair follicles return to the resting telogen phase, making it appear like you’re shedding hair.
When to see a doctor about hair growth
Any concerns regarding reduced hair growth, extremely damaged hair, or any significant changes to your hair should be addressed with a doctor. They can check for possible nutrient deficiencies and recommend specific products that may help.
If you’re experiencing unexplained and/or severe hair loss, you should schedule a checkup with your doctor, as certain health conditions can cause hair loss. In such cases, treating the underlying cause may help reverse hair loss issues.

Boosting hair growth entails healthy hair habits along with an overall healthy lifestyle. Some of the ways you can promote hair growth include the following:
- Get enough protein in your diet.

Frequently asked questions about hair growth
Can you wash your hair every day?
This depends on your hair type.
While oily and straight hair may require daily washes, you may not need to shampoo daily if you have dry or damaged hair.
If your scalp is slightly oily but your ends are not, try a dry shampoo in between washes.
Does weather affect hair growth?
While there’s a theory that hair grows faster in the summer months and sheds more in the winter, the evidence is anecdotal at best.
Any unusual hair loss should be addressed with a doctor, no matter the time of year.
How long does it take to speed up hair growth?
This may depend on the severity of any underlying hair loss conditions, as well as the treatment method.
For example, minoxidil topical treatments for hair loss may take 3 to 6 months to work, while the correction of any nutritional deficiencies can vary in duration.
Does your hair grow slower as it gets longer?
If it seems like your hair growth is slowing down as it gets longer, this is likely due to the cycle your hair is in.
Keep in mind that, while the exact timeline varies, the total cycle for each hair on your scalp is between 2 and 6 years.
The bottom line
Most of the factors that control hair growth are out of your day-to-day control.
The best step you can take is to prevent hair loss and thinning caused by poor nutrition. In other words, be sure to eat a balanced diet and stay hydrated.
Consider consulting your doctor if you experience unusual or significant hair loss. They can check for underlying causes like certain health conditions or nutrient deficiencies.
