it is natural to lose 100-200 hairs a day. Use hair oil and conditioner. shampoo alone is not good.

How long is your hair ? If it's quite long, time to go cut them, it helps.

Or maybe you can try Kérastase Paris product, some saloon also got.
I did few treatments and i can see the result, last for few weeks to 1 month+
Of course, you have to do the treatment once a week which is quite expensive.
So my hairdresser ask me to get the products myself and do it at home but also expensive la.

Hair mask + serum = 350, forget about the price for shampoo and conditioner $$$$ so I give up and use Loreal now, still dropping but it's normal as my hair is quite long liao.

a little spot with no hair by your hairline where your parting is? that's normal. if it's in the middle of your head, that's abnormal.

like uest91 said, try keeping shorter hair. long hair requires more maintenance.

I was on crash diet a couple years ago and my hair fall was like shit.. So if you're on diet, stop~

Used Grigio Toretoman Parfait (its a product for hair loss treatment that contains garlic, Ginseng and swertia extract) for almost a year, and my hair fall has been reduce to a normal rate. 

I have super dry hair too, cause I use heat on my hair daily and I swim a lot. So Wella system professional power mask is my ultimate saver!

Hope this helps =)
