The best!
Simply the best shampoo I have used so far. Better than Head &Shoulders which I have always used. Does not dry out your scalp and leaves your hair very manageable . I still have a full head of hair as a 70 year old male although a bit silvery now lol.

First time purchase and thought it was alright
I actually tried this out for the first time. It's a decent smelling product but you have to let it sit on your head for a few minutes to get the most out of it

It Works For Me !
I have been purchasing Alpecin Caffeine Shampoo 250 ml size for a while now, and found it cheaper here on Amazonthan buying it in my local pharmacy, so I thought it time to sing its praises. As an older male, I find that it keeps mygrey hair in good condition, it certainly helps with itchy scalp which can be caused by age related skin conditions ormedications, and keeps me free from dandruff.I have short hair and find that using it every other day it gives a slight thickening to my thinning hair.Whether it does live up to the TV adverts which indicate that it can prevent hair loss, I cannot say, but it does keepmy hair looking clean and fresh. I do as the instructions on the bottle suggest and leave it on my hair for the requiredtwo minutes, and feel good after using it.One interesting point of information that is printed on the bottle is that for Competing Athletes," Alpecin Caffeine can bedetected in the hair follicles"!Unfortunately it seems that all of the reviews for Alpecin are being lumped together under the one heading for AlpecinDouble Effect, which I have not tried. It would make more sense if they were listed separately thus allowing prospectivecustomers some idea of the different varieties of the product.

Keep your hair thick and full
Alpacin is my go to shampoo. It's keeps my hair thick and full, I often receive positive comments and I'm convinced this has stopped me from going bald over the years!

Best shapoo ever!!!!
I've tried so many shampoos to try and sort out my scalp and hair loss, as I've had put up with a lump bumpy sore head with large scales of skin coming off my head and everywhere for years, plus losing the hair from my hairline I was at my wits end, then I was shopping in a boots store and saw this range of shampoo and hair treatments, after only three washes I could see the difference in my scalp and after a month my scalp was totally clear and I had new hair growth along my hairline and hardly any hair loss as I would always have masses of hair on my hairbrush and in the shower,it makes my hair super soft and I use it along side Urtekram non perfume conditioner, I'm one happy lady and always recommend it to any friends with dodgy scalps. Shampoo was delivered on time, will definitely by from seller again.

Can be sure if it is effective
Bought it the second time but dont really seem to notice any great effect but likely to make myself feel better to use such shampoo. The price is not cheap but sometime can get it cheaper in Amazon than in the supermarket.
