On average, it may take around 4-6 weeks to start seeing noticeable results from using hair repair treatments. However, please keep in mind that individual experiences may vary. It's important to consistently use the treatment as directed and have patience. The condition of your hair, the severity of the damage, and the specific treatment being used can all influence the time it takes to see improvements. If you have any concerns, it's always best to consult with a professional trichologist or dermatologist for personalized advice. Remember, taking care of your hair's health requires commitment and gentle care.
