Bond repair mask, eleven weeks in: softer, not transformed

The word repair does a lot of work on a hair product label. To test it properly we did something tedious: counted broken hairs on a white towel after detangling, once a week, for three weeks before starting and eleven weeks during.

What changed

Softness, immediately and consistently. From the second use, a wide-tooth comb went through wet hair without the usual stop at the nape. That held for all 22 uses.

What did not

The breakage count. It averaged 14 short broken hairs per detangle before the test and 13 during. That is not a meaningful difference. The mask makes damaged hair feel better; we could not show that it makes it less damaged.

It makes damaged hair feel better. We could not show that it makes it less damaged.

Is it worth $46?

As a conditioner, it is one of the best we have used. As a repair treatment, the evidence from our bathroom is thin. If softness is what you are paying for, you will be happy.
