If you’ve ever longed for lengthier locks, you’ve probably tried to learn how to make your hair grow overnight. While it’s a well-known scientific fact that most healthy hair grows about a quarter to half an inch every month, there are articles aplenty boasting methods to teach you how to make your hair grow longer overnight. Mostly, you’ll find that there are mayonnaise and keratin treatments, and other sticky situations. But you know as well as we do – that doesn’t actually work as advertised.

Let’s just get it out in the open: there’s no make your hair grow overnight fast. If you come across someone peddling that premise, you know you’re barking up the wrong tree.

Instead of trying cockamamie schemes that won’t ever work, this week’s trick will teach you how to make your hair grow overnight – well, over many nights. The most important ways to achieve healthy hair growth are through optimal hair care, your diet, and the way you take care of your scalp.

Eating Right for Hair Growth

Vitamins, nutrients, and protein are the golden keys if you’re looking for long, lovely locks. The hair growth cycle is implemented at many different times for each hair on your head. The anagen stage of the hair growth cycle is also known as the growing phase, and the best way to learn how to grow your hair longer overnight is by training your locks to languish in this phase.

Did you know that protein makes up 90% of your hair? It’s a special protein called keratin, and the more protein you have in your diet, the more of it you can produce. The sweet spot for health science and nutritionists is at least 15% of your daily food intake being some type of protein.

Although any protein will do the trick, we recommend those from marine life. Fish (salmon especially), oysters, and shrimp contain omega-3 fatty acids that support a healthy and hydrated scalp. Pescatarians can rejoice, because marine proteins also contain some of the most crucial nutrients that help hair grow long, thick, and fast: vitamin B3, iron, and zinc.

Vitamin B3

Vitamin B3 is also called niacin, and can work as a form of detox for your body. Hair will shed less and be less likely to break if your diet is rich in niacin. This vitamin also makes your hair and skin look youthful and shiny.


Iron empowers your red blood cells to transmit oxygen throughout the body, and livens up your cells this way. Chief among those? You guessed it: Your hair follicles. In fact, if you’re losing your hair and you don’t think you should be, you might want to check and see if you’re anemic.


Zinc is another essential nutrient found in fish and shellfish. It keeps your body balanced by aiding in the production of the hormones called androgens. If your hair is growing slowly, falling out, or continuously filled with dandruff, your androgen levels may be low.

Don’t have the chops to eat marine proteins? No worries – simply add omega-3’s and a daily vitamin and mineral supplement to your diet. Vegetarians and vegans, especially, will want to protect their hair this way.

Secrets to A Healthy Scalp

You’ve got your vitamin game down. Now, you need to make sure that your hair has the ultimate growing environment. The best platform for this is through a healthy scalp, and one that has great circulation. If your scalp is happy, your hair will be happy. And you will look great and feel even better!


It might come second nature to you in the shower or during those tough work projects, but be sure to massage your scalp with your fingertips as much as you can throughout the day. 20 minutes is ideal, but you want to make sure to just use your fingertips to avoid greasing up your scalp’s natural habitat. If you want to go even further with scalp serenity, essential oils can be a game changer for scalp circulation and comfort. Choose essential oils that improve circulation, such as citrus oils or peppermint. If you feel it tingle, that’s a good sign.


If massaging and oils aren’t your thing, hit the running trails or gym and work it out! Blood flow increases everywhere when you’re exercising, and the cold shower you take afterwards can help, too. Cold immediately stimulates increased blood flow, as your head will be trying to get warm. When you feel a pang of energy as the cold water hits your head, you know your getting your blood pumping!


Last but not least, practicing stretching exercises where your head is upside down (or inverted) will increase the blood flow to your scalp. Yoga is notoriously good for this. Make sure your blood pressure is stable if you’re going to turn yourself upside down!

Healthy Hair Habits

If you are still wondering how to make your hair grow longer overnight, there’s one way that – over a number of nights – is sure to make a difference. Keep your ends trimmed! Split ends can make your hair brittle and dry, and aren’t a good look for anyone. Make sure to get a good haircut every other month (or more!), and minimize breakage of ends.

If you ditch the blow dryer, your ends won’t break as much. But if you’ve got to style your hair with heat, make sure to keep it below 340 degrees Fahrenheit. Any hotter and the keratin starts to break down, creating the perfect storm of problems for otherwise healthy hair.

Make Your Hair Grow Overnight: A Conclusion

You can do everything right for your diet, hair, and scalp, and you still might not unlock the secrets of how to make your hair grow overnight (or nights). Genetics is a factor in all types of health issues, including rates of hair growth. If you stimulate your scalp, have a great haircut, don’t fry your ends, and eat really healthy, your bad genetics may not matter so much! You’ll be looking and feeling great without worrying about how to grower fuller thicker hair overnight. Love your locks, and they will love you!
