Best product I have used by far for extra volume and a 3 day hold is Amargan advanced styler it is a new product. You use it on totally wet hair after you haved shampoo your hair, then you blow dry it and you will get the WOW effect. it contains Argan oil and keratin. I bought mine at my hairdressers so it may be best to contact Amargan direct to ask where you can buy it hope this helps
