I have always had problems with my nails growing & being strong. I researched online & watched many YouTube videos. I started to take biotin, hair/nail /skin supplement & vitamins and waited patiently for the results. In about a month I started to see results & I’m so satisfied with the results. My nails have not broken & they are not weak. I have a weekly regimen that I follow along with taking the supplements. I soak my nails in water, salt, vinegar & oil once a week then I put strengthener, cuticle oil & growth polish. I continue to see growth. I’m not sure how long I will let them grow. The key to having healthy nails is Patience. The other thing I do is visit the nail salon once a month & I will do a YouTube video about nail care.
