the Indian secret, to grow hair at a rocket speed and treat baldness from the first week

To remove the oil, use your regular shampoo to rinse it off. Choose a shampoo that is gentle and does not include sulphates if you are trying to avoid harsh chemicals.
Using this therapy at least twice a week is recommended for achieving obvious benefits. Consistency is the key. Within the first few weeks, a lot of people say they saw a change in the texture of their hair as well as the rate at which it was growing.
Additional Suggestions to Consider:

There are additional hair-beneficial herbs that can be added to the oil during the infusion process, such as fenugreek seeds or amla (Indian gooseberry). This can help to increase the effectiveness of the oil.
