If you’ve been struggling with thinning hair, slow regrowth, or hair that just won’t grow past your shoulders, you’re not alone. I’ve been testing popular hair growth supplements to help you decide what’s worth the investment—and what’s not.
In this review, I’ll share my honest opinion on 3 of Amazon’s best-selling hair regrowth products:
- Viviscal Hair Growth Supplements
- Minoxidil 5% Extra Strength Treatment
- Sports Research Extra Strength Biotin
Let’s dive in!
Viviscal Hair Growth Supplements for Women
Type: Oral Supplement
Key Ingredients: AminoMar® marine complex, Biotin, Zinc, Vitamin C
Use: 2 tablets daily for 3-6 months
Viviscal is a clinically tested supplement that’s especially popular with women experiencing temporary hair thinning. It’s packed with a marine complex called AminoMar®, as well as nutrients like Biotin and Vitamin C.
My Experience:
I noticed less hair shedding within 4 weeks. My hairline looked fuller around the 8-week mark. It didn’t dramatically regrow bald spots, but it helped strengthen the strands I had.
Pros:
- Clinically backed formula
- Visible results in 4–8 weeks
- Gentle on the stomach
Cons:
- Must be taken daily, long-term
- Pricier than other options

Minoxidil 5% Extra Strength Hair Regrowth Treatment
Type: Topical Solution
Key Ingredient: 5% Minoxidil
Use: Twice daily, directly on the scalp
Minoxidil is the only FDA-approved ingredient for hair regrowth, and this 5% solution is the strongest available over-the-counter. It works by revitalizing hair follicles and increasing blood flow to the scalp.
My Experience:
This stuff works—but it takes consistency. I saw baby hairs sprouting after 2 months. It helped in areas where hair was thinning but didn’t do much for completely bald patches.
Pros:
- Scientifically proven ingredient
- Noticeable regrowth within 8–12 weeks
- Affordable long-term
Cons:
- Requires daily application
- Can leave hair greasy if not applied carefully
- You must keep using it—or results fade

Biotin is essential for healthy hair, skin, and nails. This version by Sports Research uses cold-pressed coconut oil and comes in a softgel, which makes it easy to swallow and absorb.
My Experience:

Final Thoughts: Which One Should You Try First?
Here’s a quick breakdown to help you choose:

|---|---|---|---|
| Viviscal | Thinning all over | $$$ | 4–8 weeks |
| Minoxidil | Spot hair regrowth | $$ | 8–12 weeks |
