Take care of your diet
Your hair need proteins to grow, and the best thing you can do for them is to ensure that your diet includes foods rich in proteins and vitamins. If possible, you should also look into safe vitamin supplements, usually available in pills and tablets.
Avoid overusing hair styling products
If you have had a bad haircut, hair styling products are naturally your friends. You can use them to make your hair somewhat presentable, but overuse of these products will stunt their growth and lead to more breakage.
Use hair styling products only for special events and when going out in public, but avoid them during the course of your daily routine.
Don’t wash your hair too often
You should only wash your hair about twice a week to prevent excessive hair damage due to chemicals in shampoos and scrubbing during washes.
Moreover, the natural oil produced by your scalp promotes hair growth and make them thicker, but is washed away when you use a shampoo.
Coconut oil massage
Blood circulation in your scalp is very important to promote healthy hair growth. You can take some coconut oil and rub it in your scalp using your finger tips to massage. The oil will make your hair stronger and the massage will ensure better blood flow.
Brush your hair often
Brushing frequently is also good for hair growth as it stimulates your scalp and straightens your hair, allowing them to grow more freely as compared to messy hair.
Trim ends regularly
While you might think this would make it worse, but trimming ends promotes hair growth by removing split ends. Hair growth automatically slows down as they grow longer due to weak ends and split ends. Trimming them helps maintain a steady growth rate.
Get your hair restyled
Sometimes it is wiser to get your hair cut even shorter, or going for a buzz cut if your stylist has ruined your hairstyle. The buzz cut might even suit you better, and while it will take longer to grow back, you won’t have to hide your hair anymore.
Wear a cap/hat
If it’s not too hot where you are you can always wear a cap to hide your bad haircut and survive till they grow back.
Use hair clips and bands
Girls can use hair clips to set their hair in place and prevent them from frizzing up even if they are cut really short. Similarly, using hair bands is also a good idea until your hair grow long enough for you to style them properly.
