Breakage
I didn't notice my ends giving up on one specific day. I noticed it in photos: thin, see-through ends. The Nov 2020 photo on my receipts page shows exactly where it was.
I'm not a doctor and this isn't a diagnosis page. But the common reasons ends go thin and snap: dryness, heat, rough brushing, tight styles, and skipping trims. For a lot of women it's gradual — you don't lose hair in clumps, the ends just get thinner and shorter year by year.
One honest flag before anything else: if your shedding came on suddenly, comes out in patches, or your scalp hurts or flakes badly — that's a doctor visit, not a shampoo. Go rule out the medical stuff first. This page is for the slow, boring kind of breakage. Mine.
That's the whole before. No routine, barely conditioner. The 2020 photo is what "nothing" looks like.

Feb 2024 I started washing my hair like I meant it. The order: oil the night before wash day. Shampoo and conditioner built for damaged hair. Split-end mender on the ends, leave-in after. And on my part — a serum, on the scalp, twice a day. That last one is for my part and hairline. The rest keeps the hair I have from breaking off.
Most weeks. Not all of them. I was not consistent and it still worked.
Breakage stopped first — ends making it to the next trim instead of splitting off. Then, in early October, about a year into Bond IQ and a few weeks into the serum, my hairline looked fuller to me when the light hit it. I took photos the day I noticed and put them in the hairline post — hold your phone up and look.

I can't hand that to one bottle. The fuller look showed up on the whole system, used mostly-consistently for a long time. Anyone who tells you one product changed their hair in six weeks is selling harder than I am.
Start with the routine, not a miracle product. Everything I use is on my shelf, in order. And if you're not sure where to start, ask me — it's free, and I'll tell you honestly, including "see a doctor first" if that's the real answer.
Do thin, breaking ends recover?
Mine did, slowly, on a consistent routine: stronger ends with less breakage, and about a year into Bond IQ and a few weeks into the serum, my hairline looks fuller. Sudden or patchy loss is a different animal: doctor first.
How long until you saw anything?
Less breakage about a year into Bond IQ. The fuller look at my hairline took about a year.
What exactly do you use?
The full routine, in order, is on my shelf page.
Do I have to be consistent every single day?
I wasn't. Most weeks, not all. It still showed.
In the order I use it. Not sure where to start? Tell me what's going on with your hair.
