Difeel Biotin Pro-Growth Hair Mask for Hair Growth & Strength, All Hair Types, 12oz
Pro-Growth is the name of the Difeel range, and it is worth being straight about what a mask can and cannot do. This is a conditioning treatment. What it changes is how much hair stays on your head, not what happens beneath the scalp.
That distinction matters, because breakage is where most people lose length. Biotin works into the shaft and reinforces the weak points along it, so fewer ends snap in the comb and split ends form more slowly. Hair that is not breaking reads thicker and fuller over a few months for the simple reason that more of it survives to reach the same length.
Biotin gets talked about mostly as a supplement, and the version that goes on the outside of the hair works differently from the version you swallow. Here it is a conditioning agent, sitting on and inside the strand, and the case for it rests on what it does to the fibre rather than on anything happening internally.
The mask itself is a rich one. It conditions the hair and the scalp deeply, softens without weighing anything down, and leaves body and shine behind it. 12oz tub, listed for all hair types, and it holds up from 2a waves through to 4a coils.

Application tips
Clean, damp hair, and enough of it to feel coated. Apply in sections, concentrating on the last few inches where damage has had the longest to gather, then work whatever is left through the mid-lengths.
Cover with a cap and give it the time on the pack. Rinse until the water runs clear. Once a week on fragile hair, less often if yours is only slightly dry.
Results
Hair feels sturdier straight out of the shower, and that carries through to how it behaves once dry. Ends stop fraying so quickly between trims, and the comb collects loose shed hairs rather than broken fragments.
Fine and fragile textures gain body without going stiff. The visible payoff is slow, since it comes from what stops breaking off rather than from anything appearing overnight.
