I really like the Surge Ultra Max. I sometimes refer to it as the Surge grease because that is the way I use it. I dab it very sparingly onto the scalp, comb it through, and put on my bonnet for the evening. However, I haven't used it consistently enough to see if it has the growth potential of Surge 14. I like the extra moisture that it provides, especially since I have had to lay off the 14 during the winter. I can't go around with a wet head.
