Ive been doing cysteine treatment for my frizzy and dull hair for the last two years. Im wondering if its actually good for my hair in the long run or if it could cause any damage. Can you help me understand if its a safe option?

Cysteine treatment can be beneficial for hair, particularly for repairing and restoring damaged hair structure. However, it's essential to use this treatment in moderation and under the guidance of a professional stylist to avoid potential drawbacks.If you've been using cysteine treatment for two years and are satisfied with the results, it's likely that it's working well for your hair. Just remember to maintain a balanced hair care routine and be mindful of potential interactions with other hair treatments
