Seabuckthorn Shampoo?

About 11 years ago, I experienced hair thinning in my late teens (including a bald spot!) SBT's Seabuckthorn Shampoo Bar got me through the next year of my life until my hair started to return to normal. I swear that shampoo bar thickened my hair by x2 or x3 times over.

I'm now over a decade later and my hair is undergoing a thinning process again. I feel like I have about half the hair I did last year. I've gotten bloodwork in the past year and nothing was out of the ordinary there.

Turns out SBT went out of business so I won't be able to buy my holy grail anymore. Are there any seabuckthorn or overall thickening shampoo (liquid or bars) out there that y'all recommend? I'd like to go back to Seabuckthorn based products, as I had an amazing experience with it last time.

Thanks~!
