Use of castor oil (Vilakkennai or Amanakku ennai in Tamil) helps in preventing hair loss. Take two teaspoons of castor oil and add two teaspoons of shikakai powder, powdered amla, crushed fenugreek seeds, two teaspoons of neem paste, two eggs and make it into a well mixed paste.
Apply this paste copiously over your scalp and hair and allow it to stay for 30 to 45 minutes. Use mild shampoo to wash. If the treatment is continued for a period, then you can see fresh hair growth.
Hair loss can also happen due to dandruff. For controlling the dandruff, you can resort to massaging your scalp with little warm coconut oil followed by lemon juice.
Take 550 grams of methi seeds and after grinding them mix it with two eggs and apply this on your scalp. Let the mixture soak for 30 minutes.
Then use anti-dandruff shampoo for washing and rinse finally in warm water mixed with lemon juice. Do it twice a week to attain a favourable result for your dandruff problem.
Hair fall can also happen due to fungal or bacterial diseases and for such infections, you should contact your doctor or a dermatologist for best prescriptions.
