Need advice - thinning hair

I have quite thin hair that used to be a lot thicker (and im only 32 i blame years on the pill)

anyway i have tried most methods incl clip ons - and in terms of cost and maintenance they are the easiest and cheapest - the weaves come loose in about 4 weeks and itch like hell, the other methods can be hard on your hair and result in breakage, and cost a ton to maintain.

the aqdvantage of clip ons is they are always in night & close to the scalp, you can change your hairdo at will, and they are cheaper - perm ones tend to matt a lot near the nape whereas clip ons done - disadvantage is that you cant sleep in them so if the hair is so thin you dont want a partner to see it that might be a problem - and if you dont clip them in right they pull - but then the weaves hurt like hell on the first few days

As a professional, I would not do extensions on anyone currently suffering from hair loss problems.  If her hair loss has stopped, and she's not excessively losing hair, I would have her get clearance from her doctor before doing any type of hair extension.

That said, I would recommend some clip in wefts to give her fullness and length.  These are hair extensions that she would put on and take off everyday herself, and would be least likely to put too much stress on her hair.  Also, it's a cost effective solution, because once you have the wefts, there's no maintenance costs.
