I'm 23 years female. I had permanent hair straightening last year. They used matrix products for chemical treatment. So im using Matrix shampoo and conditioner from past 1 year but now im having lots of hair fall. I even apply castor oil, coconut oil and eggs hair mask every week but my hairs are still falling so much while washing. What should I do? Which shampoo and conditioner should I use now? Can I use normal shampoos like Himalaya and dove or pantene? Im scared that my hair straightening will go off if I use those shampoos. Will I loose my straightening if I use? Please help me doctor. thank you.
