The growth phase, or anagen, lasts an average of 3 to 5 years, and hair grows around half an inch per month [during this time]. At the end of anagen phase, the hair enters the catagen phase.
This is a short, transitional phase that lasts approximately 10 days, before the hair enters the telogen phase, which is a resting phase where strands are released from the follicle and fall out. The follicle then remains inactive for 3 months, after which point, the whole process is repeated.
This is when optimal hair growth happens, and it tends to slow down incrementally after that. Again, the exact speed of your hair growth or lack thereof depends on a variety of other factors as well, including your genetics, your overall health and whether you have any nutritional deficiencies. Hormonal fluctuations can also affect hair growth and shedding.
This is because your hairs aren't [getting what they need] to stay in the anagen phase long enough to reach their full length. In terms of [facilitating] faster hair growth, you want to focus on keeping a healthy hair environment for the strands of hair that are in this phase.
Again, the most important factor in helping your hair grow faster is keeping your scalp healthy during the anagen phase. One simple way to do this is to use a gentle shampoo.

The science is still limited. Still, there are limited studies and plenty of anecdotal claims that there are some essential oils that could be promising, which include:.

Hair grows out of follicles, which are small pockets inside the skin. Each follicle contains a hair root, which is made of protein cells.

There is little evidence to suggest that specialist shampoo or supplements can speed the rate of hair growth.

Rumor has it that over-shampooing can lead to broken, dry, and brittle locks, due to the cleanser stripping the hair of its natural oils. Depending on your hair type , the number of times you should shampoo your hair per week varies.
Thicker, coarser hair types can get away without washing their hair for a few days, while thinner hair types may find their hair feels greasy even after one day. In such cases, a dry shampoo can work wonders in soaking up excess grease as you await longer strands.

It might sound counterproductive when you want your hair to grow longer, but regular trims get rid of dry, damaged split ends and are necessary for natural, healthy growth.
If left untreated, split ends can work their way up the shafts of your hair strands and cause even more breakage, which means the only thing growing will be your frustration. Depending on the condition of your hair, your hairstyle, and your daily routine, you could need a trim anywhere from every six weeks to six months.
If you have a tendency to quickly and haphazardly rip a brush through your hair and call it quits, you might want to reconsider. Not taking proper care when brushing can cause your strands to break off and split—pretty much the opposite of hair growth. When it comes to brushing your hair, think slow and gentle. And it turns out the brush you choose makes a difference. While a brush with metal bristles has its purpose, a wide-toothed comb, a detangling brush, or a paddle brush with rounded bristles are all better options for gently combing through knots and causing minimal breakage.
Almost as important as what you use to brush your hair is when you choose to do so. Instead of detangling after the shower when your hair is at its most vulnerable and fragile , comb through your knots before you wash your hair. This brush is our go-to for detangling, thanks to its strong but flexible teeth and easy-to-hold shape. When going after the knots in your hair, work your way from the ends up, rather than from the roots down, to prevent the tangles from worsening.

We recommend this leave-in keratin spray to replace lost protein and create stronger, healthier hair. Your hair may not stop growing at a certain length, but it could stop once a certain amount of time passes aka the hair growth cycle.
