How do I stop hair fall and help regrowing it?

First of all, you need to understand the causes of hair fall. It may be due to stress, pollution, hormonal changes (in case of women) or due to over-exposure to sun or any chemical reagent. If you find out that your hair fall is due to the above reasons, follow the below steps

Change your hair washing habits:

Never wash your hair in hot water. Always use cold/luke warm water to wash your hair as hot water may damage hair follicles and lead to hair fall.
If you’re using any shampoo to wash your hair, never apply it directly. Rather mix the shampoo with some water as this process will help dilute the chemical concentration in shampoo.

Wash your hair atleast twice a week which will help in protecting your hair against dust and pollution.
Improve your eating habits:

Take lot of protein rich food including Milk, Almonds, Pistachios, Cashews, Dried Dates, Raisins, Fruits etc. If you’re a Non-Vegetarian you can include a lot of fish recipes in your meal.

Avoid taking too much spicy food often. Especially, pickles. And also avoid the intake of bottled juices. These food has the capability to increase your body heat which is one of the main reasons for hair fall.

Drink atleast 8 glasses of water per day. Have tender coconut and buttermilk atleast 2 times a week. This will help in reducing your body heat drastically.

Improve your combing habits:

For Women: Never tuck your hair too high or use tight hair bands. Try to keep your hair loose while sleeping.

Use hair brush to remove hair tangles. Always keep your hair brush, comb, hair bands clean by washing them regularly.

Never use other’s hair brush/comb. When a person combs his/her hair their sweat sticks to the comb’s teeth. So when you use the same on your hair, there are high chances for dandruff.

Always brush/comb your hair from bottom to top. Take a section of your hair from bottom, comb it gently to remove tangles. Follow this procedure bottom-up.

Let the teeth of your comb/hair brush touch your scalp gently while combing. That’s another way of massaging your scalp.

Tips to reduce hair fall (All the below methods are proven ones gathered from my friends & relatives who have tried them and seen results):

Avoid applying hair oil every day. This will only make your hair greasy and as a result will attract more dust and may lead to dandruff which in turn will lead to hair fall. The primary purpose of applying hair oil everyday, apart from nourishing hair, is to reduce body heat. Follow the 3rd point above instead of applying hair oil everyday. It’s recommended to apply any hair oil 1–2 hours before washing your hair or the night before.

Apply curd to your hair 1–2 hours before washing it. It’s a good source of protein and will also help in getting a smooth & shiny hair after the wash. You can also add Fenugreek powder, Curry leaves powder, Gooseberry powder, Hibiscus powder to curd before applying it.

Try this method the night before washing your hair: Peel a garlic and cut it into half. Rub it gently on your scalp in small circular motion without applying much pressure. Repeat this process until you cover the whole scalp. Prepare Massaging Oil: Now heat some 4–5 spoons of coconut oil with 2–3 curry leaves and 2 drops of castor oil.

Don’t make the oil too hot. Massage this oil in your scalp. Follow this for atleast 4 times a week. This is one of the powerful methods to stop hair fall and regrow hair. (Additional, it’s good to prepare massaging oil in a clean iron kadai)

Apply shallot onions’ juice to your scalp. Keep it for 10–15 mins before washing. This is one of the ancient methods for regrowing fallen hair.
Wash your hair with rice water. Rice water is rich in starch which will help in nourishing your hair.
Some more tips:

Don’t change your hair oil/shampoo often. Use plain coconut oil (with 2–3 drops of castor oil(optional)) which is more than enough to nourish your hair. Otherwise, consult a dermatologist and stick to the products they suggest.

Don’t cover your hair with scarf/cap often.

Covering your hair may lead to sweating and dandruff. If you happen to wear helmet, make it a habit to wash your hair 3 times a week.

Avoid taking too many chemical remedies for hair fall & hair growth and resort to natural remedies to avoid side effects.

Hope this helps!
