Topical dutasteride, especially at higher concentrations, can be effective for hair loss when combined with microneedling to enhance absorption. Users discuss the side effects of finasteride and dutasteride, with some preferring topical treatments to avoid systemic side effects.

The user is concerned about safely using RU58841 around cats and wonders if applying it 2 hours before a shower is as effective as leaving it overnight. The discussion focuses on the absorption time and effectiveness of RU58841.

The user is considering splitting their 5 mg oral minoxidil dose into two 2.5 mg doses and is asking about starting tretinoin on the scalp, questioning if it should be used alone initially or with topical minoxidil. They also inquire if tretinoin significantly improved their hair loss treatment.

Optimal microneedling routine is 1.25mm once a week with Dr Pen 36 needles. Applying Minoxidil right after microneedling may increase systemic absorption risk.

The conversation discusses microneedling techniques and the use of Minoxidil, copper peptides, EGF, FGF, ceramides, and hydration serums to enhance hair growth. It explores optimizing scalp conditions and the potential benefits of various compounds in conjunction with microneedling.

A 35-year-old shared their 5-month hair regrowth progress, using 0.5mg oral finasteride daily, topical minoxidil/finasteride once daily, derma stamping 1-3 times a week, washing hair daily or every other day with peppermint soap, and using eczema lotion for scalp health. Commenters congratulated the individual on the significant improvement in their hairline.

The conversation discusses whether finasteride's reduction of DHT and increase in scalp testosterone contribute to hair follicle miniaturization. Some participants argue testosterone does not cause miniaturization, while others suggest that even with reduced DHT, other androgens like testosterone may still contribute to hair loss.

The conversation discusses the best ethanol and propylene glycol ratio for homemade topical finasteride, with a focus on absorption and drying issues. The user shares their experience using a 50% propylene glycol, 30% ethanol, and 20% water solution, and considers adjusting the ethanol content for better results.

The conversation discusses the effectiveness of different concentrations and dosages of topical finasteride on scalp and serum DHT levels, comparing it to oral finasteride and noting the side effects seem to be fewer at lower dosages. Participants shared experiences and referenced a chart indicating similar scalp DHT reduction with 0.025% topical finasteride as with 1mg oral finasteride, but with fewer side effects.

Microneedling's effectiveness for hair regrowth is debated, with mixed results from studies. Some believe it helps with blood flow and scalp health, while others see it as largely ineffective.

User seeks advice for regrowing temples, currently using Fin, oral Min, and dermarolling. Suggestions include improving scalp environment and considering RU58841 or dutasteride.

The conversation discusses using peppermint oil for hair loss, with one user applying it undiluted to the scalp and another combining it with finasteride and microneedling. Some believe in its effectiveness despite limited scientific evidence, and also mention rosemary oil as potentially beneficial.

User taking 1mg finasteride daily for 2 years, wants to block more scalp DHT. Seeks reference for additional topical DHT blockers like alfatradiol and fluridil.

The conversation discusses the importance of taking vitamin D with food for better absorption and its potential role in hair loss. Some users also suggest taking vitamin D with K2, getting sunlight, and using finasteride for hair loss treatment.

Azelaic acid is discussed as a DHT inhibitor with no reported sexual side effects, but its effectiveness and absorption as a topical treatment are questioned. The user is interested in azelaic acid due to concerns about finasteride affecting penile health.

The conversation is about a hair loss treatment routine involving dermarolling, finasteride, minoxidil, and natural oils. Suggestions include using shorter needles for better absorption of treatments and longer needles less frequently for hair follicle regeneration.

The conversation discusses microneedling for hair regrowth, emphasizing the importance of disinfecting the scalp to avoid infections. It also mentions using minoxidil and castor oil in the treatment routine.

A new hair loss treatment, PP405, showed promising Phase 2a results with 31% of patients experiencing over 20% hair density increase without systemic absorption, avoiding hormonal side effects. The treatment is expected to be expensive, with Phase 3 trials starting mid-2026, and there is skepticism about the data's strength.

Topical dutasteride 0.05% is reported to outperform oral finasteride with minimal side effects, but concerns about study bias exist due to company funding. Some users report mixed results with topical dutasteride, noting issues with skin penetration and systemic absorption.

Daily microneedling at 0.25mm before applying minoxidil is debated, with some suggesting weekly microneedling is safer and more effective. Concerns include potential skin damage and systemic absorption, while alternatives like tretinoin are considered safer for enhancing minoxidil absorption.

Finasteride is essential for hair loss prevention, while minoxidil is optional. Additional treatments include a natural shampoo, a healthy diet, scalp massages, microneedling, laser therapy, and supplements like fish oils and biotin.

The user reported positive hair regrowth results after six months of using 0.5 mg finasteride and nanoxidil, despite experiencing initial side effects like testicular pain and changes in libido. They noted that nanoxidil was chosen over minoxidil due to less scalp irritation.

Topical finasteride that doesn't penetrate the skin could potentially treat hair loss without side effects. Current challenges include finding a formulation that remains on the scalp without increasing blood levels.

Topical dutasteride is suggested as a low side-effect treatment for hair loss, with a proposed dose of 0.025% 1ml/day. It is considered better than finasteride due to its even inhibition of DHT isoforms and lower systemic absorption.

The conversation discusses hair regrowth treatments using finasteride, minoxidil pills, and topical minoxidil, with a focus on the use of a 1.5mm derma roller. Users advise caution with derma rolling, suggesting smaller needle sizes and longer intervals between sessions to avoid skin damage and systemic absorption of minoxidil.

The user is concerned about potential hair thinning and has been using minoxidil and finasteride for a year, noticing some new hair growth. They recently started microneedling to improve minoxidil absorption and seek advice on applying it to the crown area.

The user has been using minoxidil and finasteride for 7.5 months to address hair thinning, particularly at the crown and temples, and is considering additional treatments like tretinoin and dermastamping despite having chronic scalp folliculitis. They are experiencing progress but are concerned about side effects and the effectiveness of treatments on temple regrowth.

The user treats hair loss with dutasteride, minoxidil, and tretinoin for about £280 a year by using dutasteride weekly due to its long half-life, while using minoxidil daily. Concerns about the shelf life and absorption of topical treatments were discussed, with some users suggesting alternative sources for these products.

Microneedling may not significantly enhance hair growth when combined with dutasteride and oral minoxidil, as its primary benefit is improving topical absorption. Some users suggest using a 1.5mm depth for potential follicle stimulation, but results and effectiveness vary.

The conversation discusses concerns about using a high concentration of 1% topical finasteride for hairline balding, with some users suggesting starting with a lower dose. It also mentions the use of GHK-CU peptide and the importance of considering the formulation to avoid excessive absorption.
