After washing it in the morning, mix rice powder with rose water and use it as a facial scrub. Apply it on the face, rubbing gently on the skin using small circular movements. Leave it on for five minutes and then wash it off with water. Then, mix one teaspoon each of honey and lemon juice with egg white and apply it on the entire face, washing it off after 20 minutes. Applying lemon juice, curd or tomato juice helps lighten skin colour over a period of time. Two or three times a week, mix multani mitti with rose water and apply it on the face, washing it off when it dries.My hair grows slowly and I want to have long hair. It is also dry. — JannatThe average rate of hair growth lengthwise is half an inch per month. Of course, hereditary factors may have an influence. Your diet should include the required amount of protein, which can be obtained from foods such as curd, paneer, sprouts, dals, beans, eggs, chicken and fish. Twice a week heat pure coconut oil and apply it on the scalp and the hair. Then dip a towel in hot water, squeeze out the water and wrap the towel around the head, like a turban. Keep it on for five minutes. Repeat the hot towel wrap three or four times. Use a creamy conditioner after each shampoo for dry hair. After washing the hair, apply the conditioner sparingly and massage it lightly into the hair. Leave it on for two minutes and wash it off with water. Applying curd or egg yolk half an hour before shampooing also benefits dry hair. When exposed to the sun, my skin begins to itch terribly and turns red with rashes all over. It subsides only after 3 hours. Recently, I tried waxing for the first time and the rashes and itching appeared immediately. — LakshmiYour skin is very sensitive to the sun's UV rays and you need to use a sunscreen with high SPF. Apply the sunscreen 20 minutes before sun-exposure and re-apply it if you are in the sun for more than an hour. This means you should carry your sunscreen with you. Skin that is so sensitive to the sun can also develop allergies to certain ingredients. Consult a doctor about it, so that you can take medication when the rashes and itching occur. In many cases, the allergic reaction gets progressively worse, making it all the more necessary to get timely medical help.I suffer from severe hair loss and have dandruff. — BinduFor severe dandruff, wash your hair at least four times a week, using less shampoo. Rinse your hair well with water. Half an hour before shampooing, apply two tablespoons of vinegar or lemon juice on the scalp, massaging it lightly into the scalp. Once a week, heat pure til oil or olive oil and apply it on the scalp at night, leaving it on overnight. Next morning, apply vinegar or lemon juice as recommended. Weekly henna treatment will also help. Wash your pillow cover, towel and comb daily in hot soapy water, after adding two teaspoons of antiseptic solution to it. Drink six to eight glasses of water and include fresh fruits, raw salads, sprouts and curds in your daily diet. Ask your doctor to prescribe vitamin and mineral supplements.
