I put warmed coconut oil in my hair on regular basis before washing - up to 4-5 hours beforehand. It is very oily and hard to get out, but I believe it helped me to regrow my hair thicker and stronger.
Also - I sometimes cleanse my scalp with ACV half diluted with water before washing. Apply it for half an hour or so. The smell is horrible, but hair become much stronger, softer and more managable.
It is said that it's o.k. to lose around 100 hair a day. Let me tell you - I know lose maybe 20 hair a day, at the most!
