Update: 

My fingernail that I had "French Tipped" myself chipped yesterday...and I noticed it last night.  I did the same finger again last night, and it turned out pretty good. 

I am beginning to believe the longer your nails are, the easier it is to do the "French Tip" because you do not have to worry about getting the white polish near the outer nail skin area. 

So, now my original "French Tip" manicure is still growing!  I can see the new growth at the base of the nail if I look closely...probably the new grow is not noticable to others. Because I continue to apply a coat of very light pink (natural) nail polish over the nails every 3 or 4 days or so. 

My opinion of doing your own French-Tips is very hard to do...I tried it and I just cannot hold the brush steady to get that pretty white tip.  So, I will probably not practicing doing my own French-Tips.

Before I forget, I am taking Biotin vitamin supplement, it says it is good for hair and nails. I have been taking Biotin for months and months...so, I am hoping it is helping my nails.
