Kirkland is a brand of Costco, a well-known warehouse retailer in the United States, with a wide range of products ranging from food, health products, clothing, daily necessities to furniture, and is known for its affordability and high cost performance. At the end of the century, the 10-year patent protection of Rogaine minoxidil expired, and a large number of companies entered the market, and the price of the drug, which had been high, also dropped significantly, among which Kirkland is one of the most representative brands.
 
Kirkland almost follows the formula design of Rogaine hair growth serum, the active ingredient is minoxidil, and the two products contain the same active ingredient at the same concentration, and the efficacy is almost the same as that of Rogaine. But Kirkland 5% Minoxidil is only for men, and 2% Minoxidil is for women, and it also has two types of hair growth serums, foam and drops. The foam product formula is mild, odorless, propylene glycol-free, and relatively easy to use; Drop-based hair growth lotions are usually sold in bundles of 6 bottles with only one directional pressur, which is inconvenient to use, and topical solutions are slightly greasy and take longer to dry.
 
Kirkland is used in the same way as Rogaine, twice a day in a 1mL dose, with an interval of more than 6 hours, and each bottle can be used for 30 days if used correctly. Hair loss usually increases after about three weeks of use, but with continued use of minoxidil, hair will improve in both quantity and quality.
 
It is important to note that topical minoxidil should only be applied topically directly to the area of hair loss, as application to the face or other parts of the body may cause hirsutism. It is not recommended to use other topical drugs for the treatment of the scalp while using this drug, and if you experience symptoms such as redness, swelling, inflammation, infection, or pain in the scalp, you should stop using it immediately and consult a doctor.
 
Kirkland has a very high cost performance, and the price of the male foam type (6-month supply) is about 500 yuan, which is equivalent to the price of Rogaine's 3-month supply, but the use experience is slightly inferior. There are limited ways to buy Kirkland in China, but if there are reliable channels, Kirkland can be a cost-effective choice.
