Hair loss – do shampoos or conditioners make any difference?

I always had thick hair that covers the whole head. I also had the style of the Beatles and slams into my 20s. Growing up as I’ve had more hairstyles and short hair parted on the side. More recently, an overzealous barber took off too and I showed a pronounced widow’s peak and recession of the line of capelli.La part that is recessed (temples), has a few more hairs, appear mostly as hair baby soon. Because of this and because there is no baldness on both sides of my family, I’m thinking (perhaps wishfully?) What shampoo and conditioner can make a difference. I never used the air conditioner, and use basic off scaffale.Ho noticed dandruff shampoo so I can certainly benefit from better care of hair, but I just have no idea what to use. A lot of stuff advertised on the network appear as a material Snake Oil Sales. . .
