when i removed my acrylic wraps of after years of having them on my nails were super brittle. nail tek applied every day really strengthened them. also dont forget to moisturize your cuticles daily- that was a big help too.What is the BEST nail product you ever used on your nails?
i could never grow my nails and then i found this stuff by duri cosmetics called 'rejuvacote nail growth system.' its the standard thing where you put it on every day or two and take it off once a week. but i have been doing this and going for a manicure every two weeks since september and I haven't had a single nail break and my nails are the longest they have ever been. my manicurist recommends this stuff to people and calls it magic. she says she is seeing longer nails on all of her clients since she started recommending this stuff. it is AWESOME. i think it is only sold in salons, I am not sure.
Sally Hanson, extra growth and Sally Hanson diamond strength. Fabulous.
Solar oil, Nail Tek.
GEL. DONE BY A PROFESHINAL
sally hansen :)
i heard lippman nail polish is good but a bit pricey. i really like Chanel nail colours cuz they last long, help harden my nails. the price is about 18 bucks.





i use sally hansen also and they have good strenghten nails. i think Sally beauty stores have a good brand too called i think Orly. my friend used it before and it helped out a lot!
